F-17AL Arrowhawk
http://img.photobucket.com/albums/v42/allanea/allanean%20arms/arrowhawk/arrowhawk.jpg
This design has been vetted by the Hightech Design Consortium (http://z3.invisionfree.com/HighTech/index.php?showtopic=110 )
Background:
Originally, this design has been produced by Allanean Arms engineers based on the F-17 Arrowhawk, the air superiority fighter of the Illioran Air Force, after Illioran Arms was purchased completely by Allanean Arms. It underwent multiple upgrades, specifically for improved armament and superior avionic. A new ejection seat system has also been incorporated. Like the original F-17, this aircraft is equipped with a variable-geometry wing design.
b]Airframe:[/b] The airframe is constructed of two main metals, Titanium Reinforced with carbon fibers and an Aluminum-Lithium alloy to provide the much needed strength for the variable geometry wings to even reach its super cruise speed, along with the possible G-forces exerted and yaw and pitching of the wings. The rest of the airframe is constructed out of a mix of carbon reinforced plastics to provide a light, yet strong, skin for the airframe, along with small amounts of steel and aluminum in key areas. The Actual amounts are as follows: 25% Aluminum-Lithium Alloy, 27% Titanium, 44% Carbon reinforced polymers and plastics, 2% steel, 2 % aluminum.
Propulsion: The F-17AL uses two Have-Ho LBP-220 Turbofans, rated at 45,000lbf with full afterburner, and 35,000 without, for a net thrust of 70,000lbs normally, and 90,000 in bursts. These engines were originally designed for the IG-45 aircraft, which was a high-speed, low agility interceptor platform, meant to launch missiles, and not dogfight. To accommodate the need for dogfighting, and in general, more agility, the 220 was given 3D Thrust vectoring, increasing it's Rate of climb, and it's ability to dodge missiles and get around other aircraft. To reduce it's frontal RCS, the inlets are "S" inlets, much like those used on the F-22, to reduce reflections from the engine.

Weapons: The original F-17 aspired to be a stealth aircraft and therefore had 2 internal bays. The Allaneans had no such aspirations, and although the aircraft possesses limited RADAR signature reduction measures, the internal bays were eliminated in the Allanean modification, replaced instead by a set of 14 pylons – eight mounted under the fuselage, 2 under the nacelles and 4 on wing gloves.
The F-17AL also has a cannon in it's nose in the case of a dogfight.
Avionics: The Allanean design team had eliminated most of the original design features of Illioran avionics, implanting instead a standard Allanean-designed flight computer. This computer, known as the “Agamemnon” is capable of the following features:
Projection of an HUD display onto the pilot's cornea via a flight helmet. Alternatively HUD can be displayed via ocular implants or conventionally, on the helmet surface.
Voice control.
Navigation.
Integration with SkyTux, FireTux, or any local C3 software.
It is also with the A3 Radar system. This is the basic RADAR system on all Illiorian aircraft, and uses a dual band solid state pulse Doppler radar to actively track aircraft around it up to 100NM in clear skies. It also has a passive system to identify radar waves from approximately 1.5X the effective distance of the broadcasting radar, and ways to get around it. A LADAR system is also incorporated in order to map terrain around the aircraft, and to give a 3D 360 degree picture of the area around the aircraft, to a maximum clear distance of 40NM, and a "blurry" distance up to 50NM. Finally, a FLIR system has been installed by the Allanean Arms company.

Safety:
Due to the random events that may occur during a flight or combat mission,
A Symmetriad Laertes IV Ejection Seat (http://forums.jolt.co.uk/showthread.php?t=556077) is used aboard this aircraft, and it incorporates all of its safety features.
