    ISRO's Reusable Launch Vehicles

    I don't think it will hold sufficient fuel to reach space station if this is the plan and return too.

    ISRO's Reusable Launch Vehicles

    first of all Shuttle of US is very costly and based on old technologies. India is aiming not to build US shuttle but Indian shuttle which can send 1kg at min cost to space than the rest. It will be based on 21st century technologies. Semi cryogenic engine is the factor. Because kerosene is...

    They have abandonned the study for now since 2001. Though the Idea is maverick. But it NOT related to RLV TD.

    Nope it will not convert any atmospheric oxygen to LOX. Because it is not possible. It will be stored in pressurized tanks.

    ISRO's Reusable Launch Vehicles

    there WILL be PARACHUTE WHEN it LANDS on THE STRIP. But THIS TeST was Without Parachute. Splash on water and disintegrate. This was the plan. As no Undercarriage was installed.

    ISRO's Reusable Launch Vehicles

    Most probably due to no under carriage it was designed not to recover it back.. but recover it back from re entry until it touches earth /water. There would be NO PARACHUTE. The vehicle would have made manoeuvres to landed perfectly horizontal on the water surface. Everything went successful...

    @Sakal Gharelu Ustad @pmaitra @Yusuf @sayareakd Can we have a sticky thread for Indian Space news. Outside defence and strategic issues , sticky under Indian affairs or Indian Defence?

    ISRO's Reusable Launch Vehicles

    yes it will take another 15 years to develop the new boosters, new shuttle and new engines to be accommodated. It is just a trial whether such kind of design is successful or not. With larger scale, the parameters will be large, they would require better fuel for booster. And most probably...

    ISRO's Reusable Launch Vehicles

    No (Most probably) stage 1 : boosted stage 2 : semi cryogenic For scramjet to function there are two conditions: 1) Should be already travelling at good speed to ignite 2) Enough oxygen must be there to support the ignition Contradiction: Booster will already attain enough speed to leave...

    ISRO's Reusable Launch Vehicles

    ATV and RLV are different projects. It says, ABP along with RLV are keys to cheap access to space. For ABP , it will be installed on ATV and SCE200 on RLV. Scramjet cannot produce thrust beyond 100kms of altitude . Hence making it limited to suborbital utilization. Most probably scramjet...

    ISRO's Reusable Launch Vehicles

    The technology used in US space shuttle from electronics to mechanics are 20 century technologies, that's why they retired. With advancement in fuel , material science and better communication and software India's will be 21st century space shuttle with platform to upgrade it as technologies...

    ISRO's Reusable Launch Vehicles

    Boosters can take it to 100km I don't think they will install scramjet on it on the final design. Because ISRO is developing the SCE-200 , semi cryogenic engine for RLV and ULV( heavy weight launches, gslv) top operate beyond 100km with better efficiency. altitude to reach space station and...

    ISRO's Reusable Launch Vehicles

    You mean like the US space shuttle? That will be a different design then. The whole aerodynamics will change. If you have to go like 400 km , then cryogenic engine is required on the RLV. With 60 times greater scale it can accommodate sufficient fuel to take it into the 400+km orbit with pay...

    ISRO's Reusable Launch Vehicles

    Good question. The ISRO is using maverick design. It can be SSTO or DSTO as sounding rocket can be expanded by putting one more stage.

    ISRO's Reusable Launch Vehicles

    During the descent phase, small thrusters will help the vehicle navigate itself to the landing area. It has landed but disintegrated after landing. That means.. it glided. That's why not recoverable. As design was not built for recovery @Indx TechStyle...

    ISRO's Reusable Launch Vehicles

    After the launch, the space shuttle flew to an altitude of 70 kilometres and then engaged in a free-gliding flight that started with an initial velocity five times that of sound. It then landed on a stretch of water in the Bay of Bengal some 500 kilometres from Sriharikota...

    No It's USA, USSR; Japan, France and India. China is still developing it. and they will definitely try to sabotage this program of India. So beware of these yankies.

    wings seem to be too short... i hope it glides.
