The @IAF_MCC commenced the spin flight testing of @HALHQBLR's Modified IJT in Bengaluru, today.
The indigenous Intermediate Jet Trainer (IJT) will replace the ageing Kiran aircraft fleet of the IAF.
The spin testing of an aircraft is the most crucial phase of its flight testing
+Accordingly, the testing will be gradually progressed to assess the behaviour of the aircraft till 6 turn spins to either side to meet the targeted requirement
The IJT has already been tested to its full envelope in terms of speed, altitude and load factor (`g' envelope) and hs
+ also been integrated with drop tanks as well as bombs. For a spin test, HAL redesigned the aircraft by moving the vertical tail aft n extending the rudder surface. These changes for ensuring a satisfactory spin behaviour required extensive redesign of the rear fuselage and the
+ rudder. The changes hvbn incorporated into 2 aircraft wth the involvement and clearance from certification agencies at every stage. Post modification, the 2 aircraft underwent significant flight tests to assess the general handling with the new configuration of fin and rudder.
+ These aircraft have now been incorporated with the necessary safety devices (Anti-Spin Parachute Systems). During the first flight, initially, the aircraft was taken through one turn spin to the left and right-hand sides to test the spin characteristics.

Instrumentation range is 270Kms
Synthesizer controlled transmitter wth TWT amplifier, performs wth great frequency agility ovr a wideband due to its synthesizer-driven TWT transmitter
HSTDV tested at 11 AM, 07 Sept 2020 from Dr. APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha.
The vehicle ws launched using a proven solid rocket motor, which took it to an alt of 30 km,
where the aero heat shields were separated at hypersonic Mach nO.
+
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 MACH 6 i.e. nearly 2 km/s for more than 20s.
+
The critical events like fuel injection and auto ignition of scramjet demonstrated technological maturity. The scramjet engine performed in a textbook manner. The parameters of launch and cruise vehicles, including scramjet engine was monitored by multiple tracking radars, EO
