General Dynamics F-111

The General Dynamics F-111 "Aardvark" was the first variable geometry
type of aircraft to reach a "quantity" production. The prototype F-111A first
flew on December 21st, 1964. After many changes the F-111A entered service in 1967. It
used two 82.3 kN (18,500 lbs. st.) Pratt & Whitney TF30-P-1 / 3 engines. Despite it's
"F" designation, these were not used as fighters, rather all weather precision
bombers.
The F-111C used long span wings and strengthened landing gear. 24 of these were
supplied to the RAAF (Royal Australian Air Force.)
The F-111D included advanced Mark II Avionics, which increased the cost and
maintenance.
The F-111E is similar to the "A" model with enlarged engine intakes to be
used in conjunction with the more powerful TF30 engine, which was never fitted.
The F-111F is an improved tactical version of the aircraft, with two 111.5 kN (25,100
lbs. st.) TF30-P-100 engines and simplified avionics.


There was an extended study on an improved model FB-111H to be fitted with General
Electric F 101 engines, advanced avionics, and enlarged weapons bay, however this version
also did not reach production.
An intersting feature to look for on the F-111's are the inlet vortex generators hinged
on the forewing just above the engine intakes.
