THE RUSSIAN air force has been carrying out tests on the Sukhoi Su-34, looking at the consequences of a sequential, rather than simultaneous, ejection on the crewmember remaining in the cockpit. The photographic sequence shows an ejection test being carried out from the Faustovo Flight Aviation Systems Research Institute, near Moscow. The institute uses a rocket track to power the forward-fuselage sections of aircraft under test. The images clearly show a single ejection from the Su-34 cockpit, with the starboard canopy petal still in place. Burn damage is clearly visible on the collar of one of the dummies used for the test, which is presumably the one which remained in the cockpit during the first ejection.
