Advanced Technology Vehicle successfully flight-tested ISRO

[LCA Tejas]

The Indian Space Research Organisation (ISRO) on Wednesday successfully flight-tested its new-generation, high-performance sounding rocket at the spaceport in Sriharikota, near here.

The Advanced Technology Vehicle (ATV- D01), weighing three tonnes at lift-off, is the heaviest sounding rocket developed by the ISRO. It carries a passive scramjet (supersonic combustion ramjet) engine combustor module as a test-bed for a demonstration of the air-breathing propulsion technology. An ISRO release said the rocket successfully flew at a velocity of more than Mach 6 (six times the speed of sound) for seven seconds. These conditions were required for a stable ignition of active scramjet engine combustor module planned in the next ATV flight.

“The successful flight-testing is a step ahead towards the advanced technology initiative from the ISRO in the area of air-breathing propulsion,” the release said.

The air-breathing rocket systems used the atmospheric oxygen from their surroundings and burned it with the on-board fuel to produce the forward thrust. This was in contrast to the conventional chemical rocket systems, which carried both oxygen and fuel on board, a rocket technologist said.

The air-breathing rockets, therefore, are much lighter and more efficient than the conventional rockets, leading to reduction in the cost of space transportation. That is, the cost incurred to put a satellite in orbit will be much lower.

The development of scramjet engine was complex and it involved a number of technological challenges. They included mixing of very high speed air (velocity around 1.5 km a second) with fuel, achieving stable ignition and holding the flame in addition to ensure efficient combustion within the length of the combustor, the rocket technologist said.

ATV testbed for Scramjet technologies....

 

[mrwarrior006]

are yaar already our technology is cheapest in tat tooo there are looking for room on how to reduce cost but i dont blame them coz tat technoloy is crucial

Good news! I hope they move on with the testing of HSTD as soon as possible. This would eventually help us move on towards next generation of reusable space launch vehicles (avatar) for LEO!

First step (towards RLV):



This TD is going hand in hand with other hypersonic projects in india.

wind tunnel tests of RLV design (selected twin tail over single tail fin):

design attributes of RLV:

model at display (aero india):

No idea what's the status of RLV-TD launch plans!!! It would seem that it is delayed by atleast 1-2 years.

well we can use it as a cruise missile as well, just imagine a mach 6 cruise missile..Enemy defense would be toast

reusable space lunch vehicle?

how about build a 100% made in india rocket first?

the engine of your rocket is from russia
the processor used for flight control is from the US
the whole land based control and monitoring system is imported from the west

talk about reusable space lunch vehicle?

how about build a made in india computer first, including the processor, ram, storage and etc?

Dude we build whatever we like!! I guess we do need some guidance. Decisions taken by ISRO should be based on the whims and fancies of chinese internet fanboys . I would advise you to take your suggestions to ISRO and ask them to do the same . We at this forum cannot change ISRO's plans!!! I am sure they will be very accomodating.

If you keep ranting here at on what ISRO should or should not do, it will have no use I am afraid!!

great going by ISRO jai ho!

TUMKUR: Indian Space Research Organisation (ISRO) Chairman K Radhakrishnan here on Wednesday said that the ISRO continue to scale greater heights in application of space technologies to the benefit of common man.He was delivering the convocation address after being conferred with honorary doctorate degree (D.Sc.) at the third convocation of Tumkur University on the premises of University Science College (USC).

“From a modest beginning of small sounding rockets we have graduated to powerful reliable launchers like PSLV and GSLV and with 15 consecutive successful launches the PSLV has been most reliable in its class in the industry and is also used commercially,” he added. “With the development of GSLV MK-III the launch capacity would be induced (technically 4t to GTO) further that means an adult elephant being carried to 25,000 km above earth,” he pointed out.

The other dignitaries who were conferred with honorary doctorate degrees include justice Santhosh Hegde, Sadananda Maiya, Sudhamurthy, T A Dasappa, R Ganesh and Y N Gangadhara Shetty. Governor H R Bharadwaj and TU V-C S C Sharma were present.

Jugnu ready to be handed over to ISRO


KANPUR: IIT-Kanpur with its Nano satellite 'Jugnu' is ready to set new highs in the field of space research. A team of students, working under Dr NS Vyas (the visionary man behind the making of the nano-satellite) and other faculty members of the institute, have successfully made the country's first nano-satellite to be developed for the first time by any educational institute.

The satellite will be handed over to two ISRO scientists, DVA Raghav Murthy (Project Director, Small Satellite Projects) and Dr SK Shiv Kumar (Director, ISRO satellite tracking centre), by President Pratibha Patil on March 6.

Weighing less than three kg and with most functionalities of a normal satellite on a small platform, the payload of the satellite will include an indigenously designed camera for near remote sensing and a GPS receiver. 'Jugnu' will transmit blinking signal at all times, all over the Earth. It will revolve around the Earth 15 times a day in polar orbit and will be visible over Kanpur for three to four times for a total of 20 minutes.

Head of mechanical department Dr NS Vyas while talking to TOI on Wednesday expressed happiness that the satellite had been made by the 50 students who worked as a team with utmost devotion and dedication.

Student's team leader, Shantanu Agarwal informed that the nano-satellite 'Jugnu' would be launched from Satish Dhawan Space Centre (also known as SHAR) located in Sriharikota, Andhra Pradesh, by ISRO`s Polar Satellite Launch Vehicle (PSLV) in the month of August or September after trials. "Most of the performance tests for the subsystems of satellite will be carried out at the institute, using existing infrastructure. However, launch critical tests will be carried out at ISRO centres," said Shantanu while talking to TOI.

Informing about the ground station made for controlling Jugnu, Shantanu said: "After its launch, Jugnu will be continuously monitored and controlled by Ground Station located on the campus."

The team Jugnu comprising faculty members, students and other staff members worked hard day and night to complete this mighty project in one year's time. Dr AR Harish of electrical engineering department, Dr Sudhir Kamle, HoD, aerospace engineering department, Dr V Raghu Ram (mechanical engineering department), Anjali Kulkarni (senior research engineer) and several other faculty members and the student body including Shashank Chintalagiri, Amrit Sagar, Ankush Desai, Ankesh Garg, Siddartha, Anubhav Singhla, Raghu Raj, Saket, Kshitij and several other students gave their best in the making of the satellite.

Five girls were also on board the student team. Asna, Shruti Agarwal, Ankita Mittal, Ankita Agarwal and Parul too took up the challenge like their male counterparts and contributed to the development of the satellite.

While explaining about the functioning of the satellite, Shantanu said: "The images collected will also be useful in studying the vegetation and the water bodies. The satellite design is mostly indigenous. In view of the high cost associated with the launch special efforts is being made to keep the weight to the lowest minimum."

Apart from testing many other critical systems including payload, structure, antenna, camera and communication link, students worked hard on the thermal management of the nano-satellite which was yet another important aspect of the entire satellite management.

Dr Sameer Khandekar of IIT-Kanpur who was looking closely into the thermal management of the satellite, told TOI about the use of the multi-layer insulation and high thermal conductivity interfaces and routes for maintaining the temperature of the nano satellite in space and its smooth functioning.

"The solar panels installed on the satellite will absorb the sunlight to produce photo-voltaic energy. This solar energy will generate the required electrical energy for the operation of the satellite. The electrical energy used by the satellite components generates heat. This generated heat has to be dissipated out to ensure smooth functioning of the semiconductor based electronics installed on the satellite," said Dr Khandekar.

While explaining about the use of the multi-layering insulation and high thermal conductivity interfaces for maintaining the temperature of the nano satellite, Dr Sameer added: "As there is no air (atmosphere) in the space, the thermal management of the electronic components has to be done essentially through other means. This includes the use of the multi-layering insulation and high thermal conductivity interfaces, ensuring that the heat generated inside the satellite is dissipated to outer space and, at the same time, the vital electronic components work properly."

It is to be noted here that the thermal management of a satellite has to be done very cautiously so as to avoid the collapse of its functioning in space.
