ISRO successfully conducts landing experiment of the Reusable Launch Vehicle Technology Demonstrator RLV-TD
Bengaluru: The Indian Space Research Organisation (ISRO) on Sunday successfully carried out the landing experiment of the Reusable Launch Vehicle-Technology Demonstration (RLV-TD) programme at the Aeronautical Test Range in Challakere, Chitradurga.
An Indian Air Forces (IAF) Chinook helicopter was used to drop the RLV-TD from a 4.5 km altitude and ISRO executed the landing experiment of the RLV-TD as planned.
“The RLV took off at 7:10 a.m. by a Chinook helicopter of the IAF as an underslung load and flew at a height of 4.5 km. Once the predetermined pillbox parameters were attained, based on the RLV’s Mission Management and Computer command, the RLV has released mid-air, at a down range of 4.6 km,” ISRO said.
It further added that the release of the RLV was autonomous as it performed approach and landing maneuvers using Integrated Navigation, Guidance, and control system and completed an autonomous landing on the airstrip at 7:40 am.
The space agency also said that in a first in the world, a winged body has been carried to an altitude of 4.5 km by helicopter and released for carrying an autonomous landing on a runway.
According to ISRO the configuration of RLV-TD is similar to that of an aircraft and combines the complexity of both launch vehicles and aircraft.

“The winged RLV-TD has been configured to act as a flying test bed to evaluate various technologies, namely, hypersonic flight, autonomous landing, and powered cruise flight. In the future, this vehicle will be scaled up to become the first stage of India’s reusable two-stage orbital launch vehicle,” ISRO said.
RLV-TD consists of a fuselage (body), a nose cap, double delta wings, and twin vertical tails. It also features symmetrically placed active control surfaces called Elevons and Rudder.
RLV-TD was successfully flight tested on May 23, 2016, from Sriharikota validating the critical technologies such as autonomous navigation, guidance and control, reusable thermal protection system, and re-entry mission management.
During this mission the vehicle landed ona hypothetical runway over the Bay of Bengal.
Sunday’s early morning landing experiment is the second in the series of experimental flights of the programme.
One of the key objectives of mastering the RLV technology is to achieve low cost access to space.
