Design

It is ironic that , though the F-14 has a wing able to take any angle automatically between 20 to 68 degrees according to the varying demands of the mission , it actually usage has been almost totally in the fighter/interceptor role. The main advantages of the swing wing for the F-14 includes to reduce take off and landing speed , facilitating cat ( accelerated ) launches at high gross weight and to reduce fuel consumption in subsonic loiter and enable higher altitude to be reached at low subsonic speeds.

Although the Tomcat and the A-6 Intruder are hardly more different in other way, both planes share a similar inlet duct , wing and landing gear geometry, the Latter folding forward alongside the duct into compartment faired under the wing roots. Unlike the A-6 the long fully augmented engines extend far down stream to variable nozzles at the extreme rear of the aircraft , widely separated throughout by fuselage tankage and with a canted vertical tail above each engine and the airbrake above and below the wide gap between the nozzles

The pilot and his RIO sits well separated in a capacious tandem cockpit . Aerodynamics of the F-14 tomcat are complex with a large fixed wing glove carrying the outer wing pivot 17ft and 10 inches apart and incorporating retractable canards .

When a F-14 Tomcat crashed on USS Kennedy while landing , a decision was made to replace engines on the F-14A (plus) version. This replaced the F-14A production from November 1987. The F110 engine are also being fitted to the F-14D version which introduces an almost complete suite of digital avionics which includes the APG-71 radar and a new IR search/track unit.

Avionics

The Tomcat is believed to have been the world first fighter to have a look down and shoot down capability . This capability was the last major gap to be closed in air defense. It is also claimed that the F-14 Tomcat not only have capability against hostile aircraft but also Sea Skimming anti-ship missiles.

AWG-9 radar is a large ( 1,293 lb/586.5 kg ; 28 cu ft/0.79m cube) liquid cooled package with the vital coherent pulse droppler mode for look down capability . The Tomcat was also the first fighter to have a TWS ( track while scan ) , enabling the Tomcat to have a range over 100 miles ( 160 km) to detect and select and track up to 20 target and pick out the 6 most threatening targets and launch phoenix missiles against them . Each phoenix is coded with its own target . With the help of Northrop TCS ( TV Camera Set ) the problem of long range recognition is greatly assisted .

One of the problem involving using the AIM-7 AAM was that the Tomcat needs to constantly flying toward the hostile fighter to provide target illumination for the missile

Kaiser provided the AVG-12 vertical situation display and electronically separated but mechanically integrated HUD , the HUD simply uses the inside face of the wind screen instead of a latter combiner glass .

Other kits included in a F-14 are an expandable memory digital computer, laser gyro INS ( being retrofitted when funds permit) , Westinghouse/ITT ASPJ and Hughes ITT JTIDS combined with the ITEK ALR 67 threat warning system .

49 Tomcat have been fitted to carry TARPS ( Tac Air Recon POD system ) with camera and IR Linescan .

Structure

Wing carry-through is one piece electron beam-welded structure of T1-6A1-4V titanium alloy with 6.71m span . Fuselage has machined frames , titanium main longerons and light alloy stressed skins , radome hinges upward for access to radar , fuel dump pipe at extreme tail , fins and rudder of light alloy honeycomb sandwich, tailplane have multiple spars, honeycomb trailing edges and boron/epoxy composites skins.

Landing Gear

Retractable tricycle type . Twin wheel nose unit and single wheel units retract forward. Main unit inward into bottom of engine air intake trunks. Arrest hook under rear fuselage , house in small ventral fairing.

Power Plant F-14B/D

Two General Electric F-110-GE-400 turbo fans rated at 71.56 kN and 120.1 kN with afterburn . Garret ATS 200-50 air turbine starter. F110 engine has 43 % more reheated thrust and 37% more military thrust (no after burn) than TF-20-P-414A in F-14A resulting in 20% more specific excess energy and 30% lower fuel consumption . The engine also have 62% greater launch deck intercept radius and 34 % more combat air patrol time . Total fuel capacity is 9,029l liters plus 2 external tank each capable of carrying 1,011 liters .
