DRDO successfully flight tests Hypersonic Technology Demonstrator Vehicle

      WHY IN NEWS:

  • Defence Research and Development Organisation (DRDO) has successfully demonstrated the hypersonic air-breathing scramjet technology .
  • The flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) at 1103 hours from Dr APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha today.
MINISTRY? :-Ministry of Defence
SYLLABUS COVERED: GS 3:Defence : DRDO

      LEARNING: 

For PRELIMS go through the features and significance of this launch . Note down the successfully tested technologies.

For MAINS add this event in your Mains book . This is a major breakthrough . We have attained self-reliance in hypersonic vehicles.

      ISSUE: 

On this successful demonstration, the country enters into the hypersonic regime paving way for advanced hypersonic Vehicles.

HYPERSONIC TECHNOLOGY DEMONSTRATOR VEHICLE

  • Hypersonic cruise vehicle test puts India in elite club .
  • DRDO says it will help develop hypersonic cruise missiles.

WHAT ARE HYPERSONIC VEHICLES

  • Hypersonic vehicles fly faster than five times the speed of sound .
  • This can enable faster access to space, rapid military response at long range, and even commercial air travel.
  • Traditionally, rocket boosters have been used for hypersonic vehicles.
  • A hypersonic vehicle can be an airplane, missile, or spacecraft.

Some hypersonic vehicles have a special type of jet engine called a Supersonic Combustion Ramjet.

  •  Sometimes, a hypersonic plane uses a rocket engine.
  • A Re-entry Vehicle is another type of Hypersonic Vehicle.

HYPERSONIC TECHNOLOGY DEMONSTRATION VEHICLE (HSTDV)

  • The hypersonic cruise vehicle was launched using a proven solid rocket motor.

HSTDV motor took it to an altitude of 30 kilometres (km), where the aerodynamic heat shields were separated at hypersonic Mach number.

  • The cruise vehicle separated from the launch vehicle and the air intake opened as planned.
  • The hypersonic combustion sustained and the cruise vehicle continued on its desired flight path at a velocity of six times the speed of sound i.e., nearly 02 km/second for more than 20 seconds.
  • The critical events like fuel injection and auto ignition of scramjet demonstrated technological maturity.
  • The scramjet engine performed in a text book manner.

MONITORING

  • The parameters of launch and cruise vehicle, including scramjet engine was monitored by multiple tracking radars, electro-optical systems and Telemetry Stations.

The scramjet engine worked at high dynamic pressure and at very high temperature.

  • A Ship was also deployed in the Bay of Bengal to monitor the performance during the cruise phase of hypersonic vehicle.
  • All the performance parameters have indicated a resounding success of the mission.

HSTDV PROVED THE FOLLOWING CRITICAL TECHNOLOGIES

  • Aerodynamic configuration for hypersonic manoeuvers
  • Use of scramjet propulsion for ignition

Sustained combustion at hypersonic flow

  • Thermo-structural characterisation of high temperature materials
  • Separation mechanism at hypersonic velocities.

      IASbhai WINDUP: 

MAJOR BREAKTHROUGH

  • With this technology, cruise missiles could now travel at hypersonic speeds.
  • Scramjet engine is a major breakthrough.

Air goes inside the engine at supersonic speed and comes out at hypersonic speeds.

  • The vehicle reaches a certain altitude, then cruises and also reaches very high temperatures, up to 1,000°-2,000° Celsius, during re-entry.
  • After the Anti-Satellite Test, this is the biggest achievement recently.
  • The scramjet engine performed in a textbook manner.
  • It worked at high dynamic pressure and at very high temperature.

STRENGTHENING DEFENCE CAPABILITIES

  • Secretary Department of Defence R&D and Chairman DRDO Dr G Satheesh Reddy congratulated all the Scientists and Researchers .
  • HSTDV mission is an example of resolute and unwavering efforts towards strengthening Nation’s defence capabilities.
