[WWII] Henschel Hs P.75

Henschel Hs P.75
Intended to be the successor of the Bf 110 heavy fighter (p. W:IC88), work began on the P.75 in 1941. The aircraft used a less orthodox layout, with two coupled Daimler Benz motors powering twin counter-rotating propellers in a pusher design. The wings were set to the rear of the fuselage, with canards on the nose and a tail slung to the bottom. The downward facing tail acted as a safety bumper to prevent the propeller blades from striking the ground during takeoff. The pusher prop design also mandated tricycle landing gear.

While the pusher prop gives the pilot an excellent field of view and simplifies gun installation, it makes the engine much more prone to overheating and can turn the pilot to puree on emergency bailout. Although the design faired well during wind tunnel tests, it was not pursued beyond this stage.

Despite the disadvantages of the pusher design (it was abandoned early in plane design in WWI as well), similar contemporaneous designs can be found in the Kyushu J7W1 Shinden and Curtiss XP-55 Ascender.

The P.75 uses 131 gallons of aviation fuel per hour at routine usage. A full load of fuel and ammo costs $418.

Subassemblies: Medium Fighter-Bomber chassis +4; Heavy Fighter wings with High-Agility option +3; 3 retractable wheels +1.
Powertrain: Two 1,306-kW aerial supercharged HP gas engines with two 1,306-kW props and 390-gallon self-sealing fuel tanks [Body and Wings] (Fire 13), 8,000-kWs batteries.
Occ.: 1 CS
Cargo: 4 Body

Armor
All: 2/3

Weaponry:
4xShort Aircraft ACs/Mk 108 [Body:F] (200 rounds each).*
*Linked in pairs; additional link fires all four.

Equipment:
Body: Medium radio and transmitter and receiver (10-mile), navigation instruments, autopilot.

Statistics:
Size: 40'x37'x14' Payload: 1.79 tons Lwt.: 8.27 tons
Volume: 448 Maint.: 22 hours Cost: $82,678

HT: 8. HPs: 210 Body, 240 each Wing, 20 each Wheel.

aSpeed: 491 aAccel: 9.5 aDecel: 24 aMR: 6 aSR: 2
Stall Speed 99. Take-Off Run: 700 yards. Landing Run: 980 yards.
gSpeed: 284 gAccel: 14 gDecel: 10 gMR: 0.5 gSR: 2
Ground Pressure Extremely High. No Off-Road Speed.

Design Notes:
Design speed was 448 mph; design loaded weight was 17,047 lbs. These were adjusted to the historical figures. Ammo loadouts and fuel capacity are a guess.

Nice, I was just looking at this one on Luft '46. That's a weird- but great-looking plane.
