GENERAL DYNAMICS F-111 AARDVARK INTERDICTOR & TACTICAL STRIKE AIRCRAFT

introductionThe General Dynamics F-111 Aardvark was a medium-range interdictor and tactical strike aircraft that also filled the roles of strategic bomber, reconnaissance, and electronic warfare in its various versions. Developed in the 1960s by General Dynamics, it first entered service in 1967 with the United States Air Force. The Royal Australian Air Force (RAAF) also ordered the type and began operating F-111Cs in 1973.The F-111 pioneered several technologies for production aircraft, including variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. The F-111 suffered a variety of problems during initial development and several of its intended roles, such as an aircraft carrier-based naval interceptor with the F-111B, failed to materialize.

designThe F-111 was an all-weather attack aircraft, capable of low-level penetration of enemy defenses to deliver ordnance on the target.[35] The F-111 featured variable-geometry wings, an internal weapons bay and a cockpit with side-by-side seating. The cockpit was part of an escape crew capsule. The wing sweep varied between 16 degrees and 72.5 degrees. The wing included leading edge slats and double slotted flaps over its full length.The airframe was made up mostly of aluminum alloys with steel, titanium and other materials used in places.The fuselage was made of a semi-monocoque structure with stiffened panels and honeycomb sandwich panels for skin.The F-111 used a three-point landing gear arrangement, with a two-wheel nose gear and two single-wheel main landing gear units. The landing gear door for the main gear, which was positioned in the center of the fuselage, also served as a speed brake in flight.

weaponsThe F-111 featured an internal weapons bay that could carry bombs, a removable 20 mm M61 cannon, or auxiliary fuel tanks.For bombs, the bay could hold two 750 lb (340 kg) M117 conventional bombs, one nuclear bomb or practice bombs. The F-111B was to carry two AIM-54 Phoenix long-range air-to-air missiles in the bay. The cannon had a large 2,084-round ammunition tank, and its muzzle was covered by a fairing; however, it was rarely fitted on F-111s.The F-111C and F-111F were equipped to carry the AN/AVQ-26 Pave Tack targeting system on a rotating carriage that kept the pod protected within the weapons bay when not in use. Pave Tack featured a forward-looking infrared (FLIR) sensor, optical camera and laser rangefinder/designator. The Pave Tack pod allowed the F-111 to designate targets and drop laser-guided bombs on them.
