1947. The Navy presents the XF9F-2 fighter jet

 


XF9F-2 Grumman Navy shipboard fighter using British built Rolls-Royce Nene turbojet, has extremely short tailpipe to eliminate pumping losses inherent in longer pipe models. Wing flap configuration, shown in the accompanying photos, make landing speeds of 80-85 mph. possible. The extremely long, thin pitot tubes ensure accurate airspeed readings by measuring pressures in areas of relatively undisturbed air.

Landing gear, on retractions into fuselage, is completely covered by metal panels producing clean aerodynamic lines with low drag characteristics needed for high speed flight.

Horizontal stabilizer has been moved upward into its present rather unconventional position to keep it out of the jet exhaust which produced buffeting and heat damage when conventional placement was used. 


Slow landing speeds and fast takeoff together with exceptional climb capabilities make the Panther ideal for carrier use. The performance of this plane is said to be equal to most reciprocating engine powered fighters and superior to many. (Photos by Ross-Pix)
