5 PTAE-7 :
The engine in the 350 kg thrust category (PTAE- 7 MK I) was mainly intended for PTA as replacement for Microturbo TRI-60 engine. Later this engine was upgraded to 380 kg thrust (PTAE-7 MK II). Fig-5 shows the PTAE-7 engine.
PTAE-7 engine is a turbojet engine required to power the Pilotless Target Aircraft (PTA) being developed within the country. The requirement of this engine to meet a specific aircraft application has been “light weight, low cost, short life turbojet engine of 380 kg thrust with a maximum envelope diameter of 330mm and bare engine weight of 60 kg. The engine shall be suitable for operation from a remote ground station through telecommand. The engine should have a life of 15 hours (15 – one hour flight sorties) or 45 starts or 8 sea recoveries whichever occurs earlier. Fig-6 shows the schematic sketch of the PTAE-7.
5.1 Specification :
Condition : ISA – SEA LEVEL – STATIC
Thrust : 380 kg
SFC : 1.15 kg/hr/kg.
