Bangalore-based Aeronautical Development Establishment (ADE) which participated in Bhartiya Vigyan Sammelan (BVS) Expo 2015 held in Goa confirmed to idrw.org that long-range Subsonic cruise missile Nirbhay successfully test fired on 17 October, used a Russian provided engine and Indian developed engine of similar thrust class is under development .
Russia had supplied 200 small engines of TRDD-50MT type (up to 500kg engine thrust) for unknown Missile project in 2006 and it is highly likely that same engine has been used on Nirbhay missiles while Russia refused to provide production license for TRDD-50MT due missile technology nonproliferation to India, India took up plans to develop one locally for Strategic programme.
Indian engine already has been tested on test bed for maximum RPM and have resulted in required thrust expected from the engine but test was for shorter duration . ADE will be conducting long duration test of the new engine soon at full RPM before it can enter production.
1000km long range Sub-sonic Nirbhay is a crucial missile in India’s Defence Strategic programme and will serve in Indian Army , Air-force and Navy . ADE is also planning shorter Aircraft launched Sub-sonic cruise missile which can be released from Fighter aircrafts like Mig-29 or Sukhoi-30 .
