@@JoeBiden1776 you talking like a general human, in aeronautics and space there are fking too many details and design alterations that exists. And what does this Indian space plane looks like? X37-B? I don't think so, Space shuttle? Sort of yes its "similar" in design for general public.
The red smoke is to see and study it's trajectory. This is only the 3rd test of the vehicle. And this is a scaled down model. Next tests will be with the real size model.
So the scaled up version can produce a lot more red smoke, right? Or maybe they could try purple smoke. That would be cool. (Stay away from the oranges though. Tends to get confused with hypergolic fuel exhausts, which can be very nasty)😉
As part of the test, the 21-foot-long (6.5 meters) space plane was flown by a Chinook helicopter, piloted by the Indian Air Force, to about 2.8 miles (4.5 kilometers) above the surface and released mid-air. To test the plane's landing technology, the vehicle was intentionally released 1640 feet (500 meters) off-center from the runway below, ISRO said. The plane then automatically maneuvered itself to approach the runway, and executed an accurate touchdown at the center of the runway. The vehicle used its parachute to reduce its speed from nearly 200 mph (322 km/h) to about 62 mph (104 km/h), and later deployed its brakes to decelerate and come to a stop.
That thing came in hot. But did it with machine accuracy. Who would have thunk that the job as a test pilot is the first one that robots and computers take over.
a good first step ISRO! A bigger challenge is getting it to survive reentry. I was also impressed by the sound on this video (once it finally started). The sounds are so much more tropical sounding than here!
They already qualified it for reentry with a test back in 2016. Ofcourse a full fledged orbital flight test is the next one. But they've already verified the TPS and flight controls in the reentry regime.
I don't understand the red exhaust flume coming from it. It doesn't look big enough to have air breathing engines. I can only assume they put red smoke flares on it to more easily track it's trajectory.
That's not exhaust flume. It's just red smoke to see and study it's trajectory. This is only the 3rd test of the vehicle. And this is a scaled down model. Next tests will be with the real size model.
@@eskimojo97 They are testing landing in unfavorable conditions. This is the third and final test, after all. First test was landing in ideal conditions and from there they progressively increased the difficulty.
I mean ,even as an Indian, I have to say tests fail sometimes. That's just how it goes. But i think it is concerning that they do it so close to residential a reas.
Well they also just recently, perfectly brought back a lunar soil sample from the dark side. As an Indian, it's my duty to promote positivity between asian neighbours
Red smoke is commonly used to visualize airflow in the wake of an aircraft/spacecraft. This is the third landing test, so they are trying to make the landing tests difficult for the autopilot. First test was in ideal conditions, then they progressively increased difficulty.
They should have used blue smoke. The red smoke made me think OH NO IT IS LEAKING TOXIC HYDRAZINE FUEL! STAY AWAY! Yeah, it wasn't quite the right shade of red-orange for that, but still scary.
Red colour has the highest wavelength and hence is most visible of all colours in the visible spectrum. Blue smoke for wake airflow visualization in the backdrop of a blue sky is just asking for trouble.
This is the third test, so they are testing landing in adverse situations. First test was in ideal situation and they progressively made it harder. This is the final landing test, so they obviously made it hard on the autopilot they developed.
India is outstanding in the world for its lack of adequate food supply and medical care for its excessive population. It really, REALLY, needs a space program and space plane. Well, if you can't figure out how to produce enough food, let them eat freeze-dried space rations, right?
India produces more food than it consumes. We are a food surplus nation. Our nation also provides a government-backed free healthcare scheme for the poorest half of our population. Not just in public, but also private hospitals, some of which, like Narayana healthcare, have better open heart surgery success rates than the likes of John Hopkins USA. India's space program has been an integral part of India's poverty alleviation program and has helped lift farmers and fishermen out of poverty through space-based remote sensing services like fishing hotspot tracker, water resource monitoring, crop pattern monitoring, soil health monitoring, etc. In addition, their weather satellites help identify storm paths and provide crucial Disaster management services which further protect hapless fishermen from poverty. This has helped India in its achievement of lifting 415 Million Indians out of poverty in last 15 years, as mentioned in the UN report on Multidimensional Poverty 2022. With the Indian governments collectively spending upwards of $1 Trillion each year, the fact that India spends $1.5 Billion on space each year and $2.3 Billion on giving aid to other poor countries in the world, such amounts are trivial. World Bank estimates that India has already eliminated extreme poverty with only 0.8% Indians extremely poor. And those that are in poverty (non-extreme kind) are at 12% of the population and falling fast. It will be below 3% by end of this decade.
Increase the budget, but hold the reigns tight on the spending, don't let them loose the cost-to-results factor they've got, as the products they'll make will be exceptionally efficient in use.
Don't let the looks mislead you. Under the hood, it is a proper spaceplane, with a reentry-proven Thermal Protection System, FADS, exotic materials like Incolnel, C-C CMC Composites, various Titanium alloys, etc and a superb autopilot that landed this craft at the same exact landing speed that the American space shuttle used to land with.
Those landing legs look like it came from a Boeing 727. Good luck landing that with such big profile wheels. This hopefully is just a test not an iteration.
It's only a matter of time before other nations start fielding their own re-usable systems. The fact that so many countries are just now started to develop the technical know how is a testament to American engineering in the 70s and 80s. It's also obvious that outside of SpaceX much of that cutting edge innovation has fallen and needs to be rekindled.
F you bro, America has never been helpful for India in developing any technology specially space related tech, even worse Murica blocked the cryo engine deal of India with Russia, India made its own cryo engine by itself, and don't get me started on all the sabotages than Murica have done not only in Indian projects but worldwide
Indeed. USA has a significant lead. Now I only track Indian tech and we've been closing the gap nowadays. Ofcourse it'll get harder the closer we get. Meanwhile, USA is a pioneer, so they have it the hardest trying to push humanity's boundaries.
@@DougguoD Is that so? Then how come all American spaceplanes still rely on an FADS system where the angle of attack and Mach number during flight are computed based on an aerodynamic model of the spaceplane? Because the Indian spaceplane makes use of a novel technique that doesn't rely on any aerodynamic model and is thereby faster and computationally less expensive (resource-wise, takes less power and TIME). Which means that the Indian FADS is superior to those on American spaceplanes. And how come a "familiar looking copy" of an American spaceplane has a superior FADS? Does that mean the Indian spaceplane is not a copy after all?
Why is it weird? Annual spending of Indian Governments: >$1 Trillion Amount spent every year India on Space Program: $1.5 Billion Amount spent every year by India on giving aid to poor African nations: $2.3 Billion ^Source: Budget of India (Official document) Number of Indians lifted out of poverty in last 15 years: 415 Million Indians Proportion of Indians living in poverty today: 12% (156 Million Indians) Proportion of Indians living in extreme poverty today: 0.8% (10.4 Million Indians) Source: UN report on Multidimenstional Poverty 2022, World Bank Space program of India spends most of its funds on Remote Sensing satellite constellations that directly lift Indian farmers and fishermen out of poverty through applications like satellite-based live fishing hotspot monitoring, soil health monitoring, water resource mapping, etc. Various Indian weather satellites that provide data that helps save lives and property of tens of Millions of Indians every year and prevents the backsliding of people into poverty. Various Indian communicatino satellites provide free telemedicine and teleducation not only to poor Indians in rural areas, but also to poor Africans.
Retractable wings is a cool idea but makes if you wanna fit space plane inside a fairing and if you launch at the launch configuration proposed by ISRO for this space plane you will see this space plane will act as second stage itself and will be open in atmosphere not inside a fairing. Coming to high speed part my guess is the speed of space plane will be even faster during landing after it comes from an orbital mission
Swing wing aircraft are going out of fashion because of the complexity. The only swing-wing planes that are currently being produced in the Tupolev-160.
@@zebo-the-fat maybe not but the "test" they performed on a scale of 1-100 on difficulty in the year 2024 is like a 4. If they keep that pace up they will be in space with a full scale model by 2075
@@tirepunk7367 That is not a glider. First learn what Glide Ratio is. Rating this a 4 out of 100 on difficulty further proves a complete lack of basic knowledge on the subject matter. The next test is an orbital flight of this spaceplane. Not 2075, it will be done by 2027. Despite a shoestring budget and this project being on a low priority. Amateur.
What do you mean by "even India", I don't wanna sound like I am flexing but Mr. Knowledgeable India is 4th country to land on moon, Went to Mars, have active mission dedicated to study sun, developing Human spaceflight capabilities, etc.
How long and far did that fly because to me it looked like it just was dropped, turned on the propulsion and fell to the runway. Also, what the hell is that red shit flying out the back of it?
@@JamesFAFOCreelit's called tracking flare. Same shit America uses. And it's called prototype flight test model. It was dropped from the sky to test it's landing capabilities, Avionics and autonomous features. You know to test stuff. Like America does all the time. Ever heard of beta testing.
To visualize actual airflow patters in the wake of the spacecraft. Use it to compare to the computer models, iteratively improve both the CFD model used in the computer and also the flight control law itself. That kind of thing. (not joke).
It ain't pollution of some sort of fuel chemicals its colored sooth to make the path taken by space plane after getting dropped off from IAF's Chinook visible
Red smoke is COMMONLY used to track wake airflow patterns in airplanes as well as spaceplanes. Red, because it has the highest wavelength in the visible spectrum, and thus scatters the least due to SPM in the atmosphere. Blue would have scattered away AND blue is hard to see when the backdrop is also a blue sky.
Since India hasn't yet built any commercial passenger aircraft it's something new for them. They do have two commercial jets in the works by their company Hindustan Aeronautics Limited which manufactures parts for other companies including Boeing and Airbus.
What is the glide ratio of a commercial airliner? What is its landing speed? Oh wait, I forgot I was talking to someone whose nation doesn't even have the ability to launch a single human hair to space without relying on USA or France. Its like talking to a Pakistani about space tech.
@@mattbosley3531 No. It is not. An Indian drones have been demonstrating Automatic Landing and Take-off for years now. I don't think you understand the nature of this problem. This thing flies like a literal brick and comes in at 350 kmph when it lands. It has no engines. And it sure as heck is not a glider. The entire magnitude of problem to be solved is different. They demonstrated reentry and subsequent maneuvering 8 years before they demonstrated landing for this same spaceplane. That should indicate how difficult this was.
China, India's archenemy, has an orbiter around Moon. As do USA and South Korea. Any of them could have called India out if India had faked that moon landing. They did not call India out. Because even India's bitter enemy China can't deny the truth it sees with its own sensors. Sad try m8, but nobody buys ur crap.
