HISTORY:
The sukhoi Su-47 was designed and developed by JSC Sukhoi Company in the early 1990s under the designation Su-37 during initial development. One of the distinguishing feature of the jet is it’s forward-swept wing, wgich gave the aircraft an excellent agility and maneuverability in sub sonic speeds.
The design of the wings also gave it the ability to alter it’s angle of attack and flight path very quickly while still retaining maneuverability in supersonic speeds.
The insperation for the Su-47 came from the captured german Junkers Ju 287 in the 1940s. USSR air force knowing the advantages of forward-swept wings tried to further develope this concept and explore how far they can go with this design filosofi.
The project was launched in 1983 on the order from the Soviet Air Force, to develope an aircraft using forward-swept wings. But when the USSR was dissolved, the funding for the project was frozen. But Sukhoi decided to continue the development but with only there own funding.
In the end the Su-47 ended up as a technology demonstrator for future Russian fighters, like the american counter part the Grumman X-29. Su-47 will go and influence the design chooises of many Russian jets like the Sukhoi Su-57 and so on. The forward-sweapt wing configuration was ultimately not pursued becouse it was mainly advantageous at transonic speeds, while normal wing design was superior at supersonic speeds.
DESIGN:
The Su-47 is similar in dimensions to previous large sukhoi fighters, such as the Su-35. To make the Su-47 cheaper to develope they borrowed the forward fuselage, vertical tails, and landing gear from the Su-27 family. The Aircraft included a internal weapons bay, and had space set aside for an advanced radar.
Like the immediate predecessor the Su-37, the Su-47 is of tandem-triple layout, with canards ahead of wings and tailplanes. The Su-47 also has two tailbooms of unequal length in the outboard of the exhaust nozzles. They carry the rearward-facing radar and a breaker-chute.
The Su-47 had the ability to use thrust vectoring with the PFU engine modification witch gave it a thrust vecturing of ±20° at 30°/second in pitch and yaw. Witch supported the aircraft greatly with the agility gained by other aspects of the design.
