Vacation's over and i'm back to college again, but it turned out only one lecturer (out of 3) shows up and introduction to basic pneumatic is boring anyway, so i started scribbling this on my notebook

The Firethorn Martinet (Official inventory name: B-12) was a Great War Nordenfeld Medium bomber produced by Firethorn aviation company, it was designed according to Ministry of Defense Aviation preferrence to fast bomber which, in theory, would be so fast that it could outrun defending fighter aircraft without needing defensive armament and operating in small, isolated interdictor flight

The martinet was a straightforward design of twin engined, mid wing monoplane bomber with conventonal empennage. Engine nacelle and fuselage was long and sleek with monocoque construction, the skin was stretched metal flush riveted onto the formers and stringers, engine cowling was fastened with a set of safety latches while the rest of access panels were fastened with countersunk screws. All in effort to reduce drag as much as possible

The wings had twin spar structure with in-spar self sealing fuel tanks which contained 1600 L of high octane gasoline, the wing fuel storage consisted of inboard inspar, inboard trailing and outboard inspar tanks, divided by the engine nacelle. The wings is progressively tapered toward the tip where the wing capped with squarish wing tip, The outer trailing edges were formed by the ailerons and flaps, which were the single slotted type, however the inboard flaps were double slotted type, they were hydraulically operated with mechanical override. Overall, the wing has low aspect ratio

The bomber was fitted with tricyle landing gear, with nose gear retracting backward and main gear retracting forward into engine nacelle. The nose gear well was offset to the left to allow targeting radar aerial and its related avionics on the right side of the nose.

Crew compartment was divided into two, separated with saddle shaped trim tanks on center fuselage, the tunnel are used to transfer message, ammunition and, with some effort, crew, between two compartment. forward compartment hosed the pilot, flight engineer, navigator, bomb aimer and wireless operator. the bomb aimer sat on the nose end of the bomber, fitted with parabolic shaped perspex glazing, the underside of the dome was optically flatened for bombsighting which was done with CAB-03 computerized bombsight, the nose housed two turrets with two .50 Machine guns each, normally the bombardier would operate both turred collectively, thus when he trained the gunsight to aircraft's upper hemisphere, the lower turret would automatically cease fire and vice versa, however, the turrets can be aimed individually by an extra crewman.

The pilot sit on a elevated platform over the roof of landing gear well, which can be accessed by the crews, in fact, the standard egress procedure was through nose gear door. the flight engineer sat on a jumpseat beside and slightly below the pilot over roof of avionics bay, just in front of his is the access to the nose section and bomb aimer's position.

The wireless operator sat directly behind the pilot on the left side of the cockpit, with him are myriad of radar and radio equipment necessary for the operation, he, the pilot and flight engineer all sat under a greenhouse canopy. the navigator sat further aft just between the wireless operator and the wing torque box which was level with his desk and often used as extra space for bigger maps. both navigator and the wireless operator sat over the bomb bay which can hold up to 6,000 Lbs of ordnance.

further aft is two self sealing tanks for extended range and trimming purpose, supplementing the elevator trim tab, they also balanced the bomb payload

just aft of the fuel tanks and the other end of the tunnel is the dorsal gunner position and his ammo boxes, On all examples this turret was surrounded by a coaming which provided a track for a cam operated interruptor device which prevented the gunner from shooting the tail of his own aircraft. To avoid tangling the dorsal guns, radio lead post was offset and angled to the right, clear off of gun's movement area. The Martinet used electrically-controlled turret equipped with two .50 machine guns
Just behind Dorsal turret position located a toilet and flare launchers

the tail gunner is located on the extreme end of the aircraft equipped with electronically operated casemate housing two .50 machine guns, the ammo boxes are located forwrd of tail main bulkhead. Later variants of martinet equipped with gun laying radar for night operation

All the controls were triple redundant hydraulically operated with mechanical reserve

The Martinet was powered by twin Nordenfeld RT3000.46 two row 9 cylinders radial turbocharged engine, the power system was modular designed and could be maintained easily, the engine plus its cowling can be swapped in under 4 hours while the whole nacelle can be swapped in about 9 hours. the long nacelle also contain the main landing gear and its equipment. Turbocharger was located on the rear of the nacelle, with turbocharger exhaust on the extreme end. Compressed intake air has to travel through the nacelle diminishing the need for an intercooler, however intermediate compressor is needed to keep the air pressure high. the radiator, oil cooler and oil tank was armoured and located behind engine firewall, the wheel is located near the radiator exhaust to keep the rubber warmed on high altitude while a heat exchanger provide warm air for de-icing purpose

The name 'Martinet' is a homonym, has double meaning, it could mean a Swift or a Hammer which ephasized its speed and striking ability, the project motto is 'Strike like Martinet, Swift as Martinet'

TL;DR, just some ideas i had in mind, if you had suggestions please tell, i'll be more than glad to hear
