TOMCAT

Description

The F-14 Tomcat is a supersonic, twin-engine, variable sweep wing, two-place fighter designed to attack and destroy enemy aircraft at night and in all weather conditions. The F-14 can track up to 24 targets simultaneously with its advanced weapons control system and attack six with Phoenix AIM-54A missiles while continuing to scan the airspace. Armament also includes a mix of other air intercept missiles, rockets and bombs.

The Tomcat is a 2-seat, twin-engine fighter with twin tails and variable-geometry wings. Its general arrangement consists of a long nacelle containing the large nose radar and 2 crew positions extending well forward and above the widely spaced engines. The engines are parallel to a central structure that flattens towards the tail; butterfly-shaped airbrakes are located between the fins on the upper and lower surfaces. Altogether, the fuselage forms more than half of the total aerodynamic lifting surface.

The wings are shoulder-mounted and are programmed for automatic sweep during flight, with a manual override provided. The twin, swept fin-and-rudder vertical surfaces are mounted on the engine housings and canted outward. The wing pivot carry- through structure crosses the central structure; the carry through is 22 ft (6.7 m) long and constructed from 33 electron welded parts machined from titanium; the pivots are located outboard of the engines. Normal sweep range is 20 to 68 deg with a 75-deg "oversweep" position provided for shipboard hangar stowage; sweep speed is 7.5 deg per second.

For roll control below 57 deg, the F-14 uses spoilers located along the upper wing near the trailing edge in conjunction with its all-moving, swept tailplanes, which are operated differentially; above 57-deg sweep, the tailplanes operate alone. For unswept, low-speed combat maneuvering, the outer 2 sections of trailing edge flaps can be deployed at 10 deg and the nearly full-span leading-edge slats are drooped to 8.5 deg. At speeds above Mach 1.0, glove vanes in the leading edge of the fixed portion of the wing extend to move the aerodynamic center forward and reduce loads on the tailplane.

The sharply raked, 2-dimensional 4-shock engine intakes have 2 variable-angle ramps, a bypass door in the intake roof, and a fixed ramp forward; exhaust nozzles are mechanically variable. Viewed from ahead, the top of the intakes are tilted toward the aircraft centerline; from above, the engines are canted outward slightly to reduce interference between intake airflow and the fuselage boundary layer. The engines exhaust through mechanically variable, convergent-divergent nozzles.
