Scramjet Engine

News– The Defence Research and Development Laboratory (DRDL), a unit of DRDO, recently achieved a successful ground test of a Scramjet Engine, operating for more than 1,000 seconds in Hyderabad. Scramjet Engine.

About Scramjet Engine

• A Scramjet engine (Supersonic Combustion Ramjet) is an improved version of the Ramjet, designed to operate at extremely high speeds.
  • A ramjet is an air-breathing jet engine that relies on the vehicle’s forward motion to compress incoming air for combustion, eliminating the need for a rotating compressor. It operates efficiently at supersonic speeds, typically between Mach 3 and Mach 6.
• Scramjet works by using supersonic airflow to generate thrust and functions at hypersonic speeds (Mach 5+).
• Key features:
  • Air-Breathing Engine: Unlike traditional rocket engines, Scramjets use atmospheric oxygen for combustion, eliminating the need to carry heavy oxygen tanks.
  • No Moving Parts: Scramjets rely on supersonic airflow, making them highly efficient for sustained high-speed travel.
• Significance:
  • Next-generation hypersonic missiles with unmatched speed and accuracy.
  • Faster air travel, potentially reducing flight times drastically.
  • Low-cost satellite launches, making space access more affordable.

Hypersonic Missiles 1. These missiles can fly at speeds of at least Mach 5 (five times the speed of sound). 2. A key feature of hypersonic missiles is their Mid-Flight maneuverability, unlike ballistic missiles that follow a fixed path. 3. There are two types of hypersonic weapons: a. Hypersonic Glide Vehicles (HGVs): Launched by a rocket and then glide to the target. b. Hypersonic Cruise Missiles (HCMs): Powered by air-breathing engines or “scramjets” after locking onto the target.
