Is atmnirbhar full proof for future?
Few days ago our PM Shri Narendra Modi ji announced a great program for indian local businesses and manufacturing units which will definitely beneficiary for indian economy and in future higher stand of India in world trade.
But is this atmnirbhar is full proof ?
As according to me I think there are some points which is neglected by government which may make big trouble in future.
1. In atmnirbhar they only promot indian local brands and items. But what about other brands and items which are developing by international companies in India which are making a huge numbers of employment and revenue in india by there manufacturing units in india.
By ignoring them we are closing our doors for higher investment from the world in india. Specially recently most popular Companies which are looking for alternative from China.
2. By announcing that program india may be targeted for trade war and even so other countries think 2 times before investing / helping India whether it's for trading or any other things.
Recent example USA stop apple and all other companies to invest in india which is great opportunity for India to develop.
3. Because of that other countries companies going to cut down the strength of indian workers there. Because of that India will be losing a huge amount of foreign currency.
As according to my thinking India must includes these point
1. Indian government must promote local + those brands or items which are manufactured/ developed in india. Because of that more and more multinational companies look India as a good market and invest in india.
2. Indian government must make sure that they have a control on that investment. I mean they must control and look to whom they have to allow for investing.
3. They also promote indian companies for established plants in developing countries who had less week currency compared to India. So then they can make more cheap products and increase our trades and in return of that reliable tax increment will be make indian revenue a good profit.
4. Talk to other countries and convenience them to invest in india.
Idea for VOICE
E eager youths
In india we all called us a world's biggest democracy but if we talk about voice of all we always found only few people in front of billion people population.
In india every 5th person have there own issues and opinions for each debates but these voice never get chance to get forward whatever he/she have valid point to open voice.
According to Indian constitution every one have a rights to speak , write and express his opinion and feeling but how much this word is in practical. We saw many cases everyday whether it's criminally or kind of mental crime by using bribes for work, misbehaving by higher class of officers. We have thousands of reports for physically crimes but what about mental crimes which is mostly feel by everyone randomly or to be say everyday in many ways.
Government always says that there is freedom of speech but I want each and every single person of country to speak but then I realised that there is no network for handle that much things.
There is a huge demanding for government jobs because of stability like we you get government job that means now no one can remove you from job. And because of that mentality every 12th person in government job easily take bribe openly and not only him doing these things even higher officers are also habitual for this so then there is no action for that. So as on results what a common man get in terms to say Development is only 30-40% what actually government announced for us. Even so many of officers say that if government announced 100 then only 25 is implemented on ground.
Thousands of voice are get open for all these but non of them reach to destination and because of that many more such things happen.
Many more such things happening like workers wages, food for people ( rashan ), many benefits which are announced for farmers, workers and middle class but only few of them are delivered and many more and more ........... And even so some private / local bodies are also one of the part for all.
People wants to get says for this but a huge paper work and less point of contact more then of 90% are just vanished in this dark world and those who get noticed mostly from them also get dust in files.
So my question is to government
what are the steps taken by government to make India full democratic country??
Here I am sharing my ideas which may be helpful to make India more connecting and also using this idea huge number of youth get working experience with government and we can reduce employment issues a little bit.
For my idea voice we both ways to contact online( through the app) and offline(address in each district of India) and it will make a huge network of people.
As according to my ideas these representative from each state and one from india level will make statistics of complaints/suggestions/idea ( which comes from district level) and after analysis make a report on monthly basis and submit it directly to State CMO and Indian PMO for further steps.
Idea of voice is as follows:-
1. We have to develop a app with name voice where people have options to write complaint , suggestions or ideas on district / State / country level.
2. For district level complaints Indian government must hire 2-2 young people in each district of India as on internship basic for 3 to 6 months according to performance. Here I am not asking to hire on permanent basic because using this internship we can increase number of experience youth in administration and also more reliability of work and also using that we can save a huge amount of money from salary because every intern must be laying between salary of 20k -25k which is much less compared to a normal government employee.
These young professionals will work under most of local government bodies in combined to gain experience but its ordering and reliability must be under only voice department which will control by only CMO( state level) and PMO( India level) and non other departments will have right to ordered this department.
Main frame of working for these interns is must be like that:-
a. Every week one day they have to arrange a open meeting with shortlisted people who write them complaint/ suggestions. For Shortlisting DM and SDM office can help them.
b. After listening those they have to file complaint ( if it's have such big issue) under state head and for rest coordinate with local bodies to understand there working and look if there any issue or steps can taken to develop them and every week make file for all these work and forward to state head so then they can make statistics as according to it.
c. Write weekly basis blogs on voice app for district level program run by government and also spread awareness in local people.
3. For state level government select one IAS level honest for state head and hire 2-4 people on internship (as according to step 2) who will work under him to coordinate with district interns and making statistics and analysis.
Main frame of state level working:-
a. Coordinate with district level and make statistics and analysis every week and submit weekly report to CMO and meet with CM and other twice in a month for discussing and suggestions for further steps and also includes some of the shortlisted complaints/ suggestions ( which are beneficial for state level ).
b. Submit individual report by each and every member of state committee to India head(3-4 reports by each state) once in a month. Meet with PM sir and india team once in 60 days (all states at same place) for discussion and submitting our individual suggestions.
c. Write weekly basis blogs on voice app for state and national level program run by government and also spread awareness in all state people for programs which are beneficial for them.
4. For india level government select 2-3 senior IAS level honest officers and hire 8-10 people on internship (as according to step 2) who will work under those officers to analysis reports comes from state.
a. Coordinate with state level and make statistics and analysis every month and submit it to PMO and meet PM sir and other departments once in a month for discussing and suggestions for further steps.
b. Arrange meeting with all state individuals once in every 60 days. Write weekly basis blog for steps taken by central government and spreading awareness about government programs.
Hypersonic future of space, defence and aerospace
What if the economics and technical challenges of hypersonic flight were conquered and the once exclusive world of Concorde-style travel was replaced with hypersonic possibilities?
Imagine the possibilities of an aircraft capable of sustained flight at Mach 5.5 and beyond at altitudes above 60,000 feet on the very edge of space. The speed of hypersonic flight would mean that I could have breakfast in London, fly to Singapore in time for a dinner meeting in Dempsey Road and then fly back to India in time.
Hypersonic systems are highly maneuverable, travel many times the speed of sound, and allow for the destruction & travel at any point anywhere in the world in less than an hour. Hypersonic flights are a growing and extremely complex threat to our national interests. Currently, 23 nations have demonstrated varying degrees of expertise in hypersonic technology…a number that continues to grow daily. Hypersonic is really about industrialization, not about science…Are we technically prepared?
If you've been following defense or aerospace news in recent years, you may have noticed that there's been significant buzz about hypersonics. The USA, China, Russia, Germany, Britain, India, Australia, and even Indonesia have been conducting research into various aspects and problems of flying at Mach 5 (3,800 mph, 6,125 km/h) and above.
Now before go further let first know the basics.
Hypersonic is flight through the atmosphere below about 90 km height and at min. speeds above Mach 5, at this speed dissociation of air begins to become significant and high heat and pressure loads at which mostly material changes its physical properties.
At this speed the air flows around object forms a shock waves which deflects the air from the stagnation point and insulates the flight body from the atmosphere. And the Power of these shock waves can calculate by that there is a book name shock waves was published by the world bank group in Climate Change and Development Series.
But still There are numerous projects are running in the world some of which are:-
United States Aerojet General X-8
United States North American X-15
United States Lockheed X-17
United States NASA X-43 (uncrewed)
United States Boeing X-51 (uncrewed)
China DF-ZF (uncrewed)
Russia Avangard (uncrewed)
India HSTDV (uncrewed)
United States Space Shuttle orbiter
Soviet Union Buran (uncrewed)
India RLV-TD (uncrewed)
United States Boeing X-37 (uncrewed)
China Shenlong (uncrewed)

Soviet Union BOR-4 (uncrewed)
United States Martin X-23 PRIME(uncrewed) and X-24
United States ASSET (uncrewed)
Japan HYFLEX (uncrewed)
There are huge numerous potential advantages of hypersonic flight , including reduced travel times, improved space access and also cutting down the cost of space programs. And as today's we can see lots of defence reports for hypersonic flight. These reports should worry military analysts is fairly obvious because at the moment, defense systems operate at supersonic speeds and below. Fighter planes, bombers, missiles, anti-missiles, and artillery shells all fly at less than Mach 5. Even the fastest manned jet plane ever built, the now-retired SR-71, could only manage Mach 3.5. The only weapons that do count as hypersonic are ballistic missiles that fly out into space before returning to Earth, which makes them a very special case and same for the space programs we use huge rockets which took a high amount of resources and money in form of fuel.
As on current situation The United States, Russia, and China are leading the race to develop hypersonic missiles, with France and India close behind. Japan, Australia, and Europe are all developing the component technologies, in some cases for ostensibly civilian purposes. Within ten years, hypersonic missiles are likely to be deployed and potentially offered on the international market.
Hypersonic weapons use advances in electronic capacity, sensor quality, and miniaturization to create a new threat for world,” says Trey Obering, Booz Allen executive vice president. As former head of the Missile Defense Agency (MDA), he has a first-hand perspective. “They’re fast and maneuverable. That combination creates a threat that is imperative for the world to address.”
In fact, it is in the interests of the world to reduce their exposure to this new threat. Russia in particular has been vocal regarding the dangers of hypersonic missiles, perhaps due to a fear that NATO could mount a devastating hypersonic attack. Further, China can be expected to oppose both Japanese and Indian acquisition of such weapons or in short we can say that hypersonic is the second biggest threat after nuclear weapons.
But still there is lots of potential to be developed that's why world and many engineering expertise are working for that. From all these potential we have one is hypersonic glide vehicles can travel higher Compared to a ballistic (parabolic) trajectory, Hypersonic cruise missiles, which are powered by scramjet, are restricted below 100,000 feea but a hypersonic vehicle would be capable of large-angle deviations from a parabolic trajectory.
For example of ballistic missile a joint Russian-Indian company has started the development of a cruise missile capable of flying at Mach 5, which will make it 'impossible to intercept'. BrahMos-2 will be the next generation of the highly successful the BrahMos missile already used by Indian military. And some of hypersonic ballistic missile in all over world are as follows:-
United States AGM-183A air launched rapid response weapon (ARRW, pronounced "arrow")
As for that first step of glide vehicle as a testing we will develop a Hypersonic cruise missile which can Launches from an aircraft and uses a scramjet engine which “turns on” at hypersonic speeds to power the weapon. And for that there are multiple options one of them is indian missile Astra which can carry 15kg war head at max. Speed of mach 4.7 and most importantly can launch from many aircrafts. After this we will develop intercontinental missile systems. Basic idea made by me is written further as a Idea 1.
Then after completing first step we could step further for space launching using structural and technology from hypersonic cruise missile design and development. At this step we will boost our main glide vehicle will gain a speed above mach 4 or 5 through a solid booster rocket. Using that we can reduce around 50% resources which is used in form of fuel and also can make space flight reusable and also reduce space garbage. Basic idea for that made by me is written further as a Idea 2.
Whole world expertise in engineering complex systems is working to realises these benefits and trying to fasten the life of world and technology but hypersonic technology itself offers hope, as it is extremely difficult to master. Igniting the engine of a hypersonic cruise missile has been compared to lighting a match in a 2,000-mile-per-hour wind. Moreover, the shape of the missile changes under the rigors of hypersonic flight, creating great challenges for flight control.
World is demonstrating our capability in flight vehicle design and testing, and creating technologies to overcome the many technical challenges associated with hypersonic flight. Friction from the atmosphere exposes the air frame to extreme temperatures. We need materials and strategies to cope with the high temperature, which threaten to melt and warp the structure.And to counter drag, we seek propulsion systems that are efficient and effective at high speed. We currently rely on traditional rocket engines to provide thrust above Mach 3 to 4. These are generally unsophisticated and inefficient.
The designer of an efficient supersonic aircraft must take shock waves into account, and will generally select a slender, sharp geometry, such as that of Concorde, which keeps the shock waves as weak as possible. At hypersonic speeds it is even more important to control the strength of shock waves, and this leads to an entirely different design philosophy for hypersonic aircraft compared with their more conventional cousins. Behind a hypersonic shock wave the temperature at the leading edge of a hypersonic craft scales inversely with the square root of its radius of curvature. In other words, the sharper the leading edge of the vehicle, the hotter it will get. This is why spacecraft are designed with rounded noses and very blunt wings – characteristics that also increase the drag force. Air-breathing hypersonic vehicles are not able to tolerate this added drag, and so they will be built with sharp leading edges instead.
When a Space Shuttle returns from low-Earth orbit, the atmosphere begins to have a noticeable effect while the craft is still travelling at Mach 24. The blunt leading edges of the Shuttle offer poor aerodynamic performance but generate relatively low temperatures of 1400 °C. This is a modest temperature by hypersonic standards.This is a modest temperature by hypersonic standards, but still hot enough to melt the structure of the vehicle if the heat-protective tiles are breached. But still many Various companies and universities in Japan and Europe, including Snecma in France and Wacker Ceramics in Germany, are also pushing back the manufacturing, fabrication and performance limits of high-temperature materials for hypersonic flight. Researchers at Snecma, for example, are specifically developing high-temperature parts for the inside of a hypersonic engine.
Incorporating the sharp aerodynamic configurations of hypersonic flight into an aircraft means adopting a whole new design paradigm. Instead of fighting the shock wave, need to use it to our best advantage. One very promising design is the so-called waverider airfoil, which actually rides on top of its own shock wave for highly efficient flight.At the University of Maryland have designed waverider wing and body combinations that have very high lift, low drag and offer plenty of volume for holding payloads and fuel. Moreover, the shapes are well integrated with the engine system. These sleek designs – which range from missiles to space launchers – have been tested in wind tunnels and in computer simulations and practically project by Boeing X51A is running from last 7 years.
Basic Idea for testing of Scramjet model ( glide vehicle ) :-
In this testing we are using a sounding rocket (astra missile)which have weight of 158 Kg. Which achieve proper mach number 4.5 for stage II scramjet model and also used to obtain a certain altitude (27.5 Km) with testing project weight 15 Kg. After reaching at mach 4.5 let suppose at time t=40 sec. our scramjet stage II will release and start free fall for 2 seconds and because of that free fall it achieve mach 5.5 to 5.81 speed at t=42 seconds.
During testing our stage II will start let suppose at or after after t=42 second and runs for next 10 seconds and achieve Mach number 7.4 to 7.6 from Mach number 5.6 using 1.3 Kg of liquid Hydrogen fuel.
Total height of model will be 1.21 meter
Total height of project will be 3.5 + 1.21 = 4.71 meter
And diameter of model will be 127 mm
Diameter of missile will be 178mm.
Basic design and performance of stage II Scramjet model:-
For it's whole body we use material PBN (polymer Boron Nitrade) as it's basic design and we use both kinds of w-BN and c-BN at a time for heat fearing over silica aero gel and make nanolayer sandwich design where silica aerogel is located between both kind of BN. Thin spray of this heat fearing material will provide high heat and pressure performance with no melting point and also provide higher conductivity with repaid cooling property at lower the cost compared to other materials.
As insulation we use combination of rubber + EPDM + Boron oxide which provides a high heat resistance and also protect our body to react with air and other gases.
In this design we used a Advance design for air mixing as on figure we can see two side waveriders air frames which allow us to use two scramjet at a time which will gives us a higher trust and more controllability over model. And also as we saw a aerospike structure which have 2 advantages first it will reduce the effects of shock wave at back of our model and also we will use to generate a low pressure region which is useful us to generate power to our turbine system which pressured He ( helium ) and that will pressures our fuel tank and then a electric motor separate equal fuel in both combustion Chambers.
And as we increase Mach number exit nozzle pressure is also increase which increase our pressure on fuel tank and so on extra fuel is delivered to combustion Chambers and this process continues till fuel tank empty.
Fig. Mathematical calculated performance of scramjet for 10 sec.
As we go further in our research and in our studies in space and communication sector.we required new devices and as per NASA we have thousands of objects in our orbit and most of them are space junk (old satellites, pieces of spent rockets, waste from astronaut suits and other
items) and we are continues that but what if we can made such satellites which can do multiple works at a time and can change their own working as per future requirements. Then an idea steps in mind of world that we can use scramjet engines for launching. But till today this idea is look like a dream and there is few knowledge for this available and only few people's in world have a Idea for that.
But still I made a simple rough idea for launching through using scramjet (which’s rough notes are attach) which I named RAL (reusable advance launching) and during calculation I took weight same for all time in stage 2a just for rough calculations.
