ASLV | Augmented Satellite Launch Vehicle | ISRO Aerospace

ASLV stands for the augmented satellite launch vehicle. The Augmented Satellite Launch Vehicle (ASLV) program was conceived to raise the payload capability of Low Earth Orbits to 150 kg three times SLV-3 (LEO). Based on the experience from the SLV-3 missions, the ASLV has proven to be a low-priced intermediate vehicle for demonstrating and validating crucial technologies required for future vehicles, such as sleeves, inertial navigation, bulbs, vertical integration and closed-loop management. The Polar Satellite Launch Vehicle program and the ASLV program were not funded at the same time and after the original emerging flights, the ASLV program had been cancelled. ASLV’s payloads were Rohini Satellites Stretched.

Construction of ASLV

  • A five-stage rocket.
  • Solid explosive substance and fuel have been used.
  • The explosive substance is made up of chemicals.
  • Hydroxy-Terminated Polybutadiene (HTTP).
  • Lactone-Terminated Polybutadiene (LTPB).
  • Weight: 40 tonnes
  • The height is 24 meters.

Vehicle Understages

It’s a 5-story car that uses powerful propulsion in the five levels. The length of the lift is 24 meters and weighs about 40 tons. In the early 1980s, the ASLV project started to establish the technology necessary for the geostationary orbiting of a payload. ISRO has already perfected the strap-on technology used in the ISRO PSLV programme. The ASLV payload was extended by the Rohini array. Four development flights from the SLV launch pad in the high altitude range of Sriharikota took place under the ASLV programme:

  • On 24 March 1987, the first production flight took place. It didn’t work.
  • On July 13, 1988, the second production flight took place. It didn’t work.
  • On the 20th of May 1992, the third production flight took place. It was a partial breakdown.
  • On 4 May 1994, the fourth production flight took place. It was a huge success.

A launch vehicle is hugely difficult for dealing with the difficulties and altitude range of flying coping with the earth’s atmosphere. It should have a fine length defined trajectory. To achieve the right velocity for the satellite, it needs to placed in the correct orbit. Unlike satellites, a specific and particular technology cannot be used due to fear. With the Missile Technology Control Regime in place, such imports became impossible. The ISRO had developed and designed its vehicles, especially from the scratch. As a result, satellite development has beaten the vehicle launch programme in terms of launching.
