Sukhoi T-4, or "Aircraft one hundred", or "Project one hundred", or "Sotka" was a Soviet high speed reconnaissance, anti-ship and strategic bomber aircraft that did not proceed beyond the prototype stage.
Despite design similarities, the Sukhoi T-four was not intended as a Soviet equivalent of the North American XB-70 Valkyrie supersonic bomber, but was rather intended to take benefit of several of the XB-70’s aeronautic innovations to create a smaller sized reconnaissance and anti-carrier aircraft capable of reaching Mach 3. It participated in a Soviet competitors to develop a bomber as described above. It lost to the Myasishchev, and eventually the Tupolev design which now exists as the Tupolev Tu-160 "Blackjack."
The T-four was made largely from titanium and stainless steel, and featured a fly-by-wire manage technique but also employed a mechanical program as a backup. The aircraft’s nose lowered to offer visibility in the course of takeoff and landing. A periscope was utilised for forward viewing when the nose was retracted, and could be employed at speeds of up to 600 km/h (373 mph). Braking parachutes had been employed in addition to conventional wheel brakes.
The very first T-four, designated "101," first flew on August 22, 1972. The test pilot was Vladimir Ilyushin, son of famed aircraft designer, Sergei Ilyushin (ironically Vladimir in no way served in his father’s bureau), and navigator Nikolai Alfyorov. It has flown only ten instances for a total 10 hours and 20 minutes. It is believed to have reached at least Mach 1.three making use of 4 Kolesov RD36-41 engines. These engines each and every made 16,000 kgf (35,300 lbf or 157 kN) thrust with afterburners. The aircraft was created to attain speeds of up to Mach 3., but the plan was canceled prior to the complete efficiency of the aircraft could be reached. Sometimes it was incorrectly stated that T-4 is the "aircraft 101" that set a 2,000 km circuit speed record of Mach 1.89. In reality, "aircraft 101" is Tupolev Tu-144D.
One more purpose of canceling the project due to the VVS (Soviet Air Force) issuing the requirement of 250 T-4s. Meanwhile, some other higher rank officers argued into gaining other a lot more practical and supportive fighters as an alternative of having such a massive flying titanium plate in the air. When Marshal Andrei Grechko was made the Minister of Defense, he was told by a employees, "You could have your enormous MiG-23 order only if the T-four would be abandoned".
One particular T-4 survives today. Aircraft "101" is on show at the Central Air Force Museum in Monino close to Moscow. The serial numbers of the prototypes had been "101" to "106". Only "101" and "102" had been constructed, other additional prototypes "103" and "104" have been beneath building, "105" and "106" only existed on draft charts. Only the "101" completed all the test flights and flew the final test flight ahead of the project was canceled on January 22, 1974. The rest of prototypes have been scrapped.
