[SU1946] Junkers Ju EF-127Z Rocket Interceptor

9,428 vcharng  4.8 years ago

SU1946 stands for Simple Universe 1946, it is a series of late-WWII (or prototypes) planes plus some fiction. Planes in this series would have significantly better performance than their historical counterpart, and would receive a "Z" in their names to distinguish them from other, more accurate replicas.

Features:
- Working rocket booster with automatic detachment
- accurate skid-type landing gear
- accurate takeoff carriage
- very good dogfighting performance

History:
This is the Simple Universe version of Junkers EF-127 "Walli" rocket fighter, which takes off with rocket boosters, jettison t/o carriage, and land on skids.

IRL only the pulsejet sibling EF126 was acquired and tested by the Soviets, but since my previous work of Kostikov 302, which features another speed-triggered engine, was basically ignored by the community, I decided to make the Rocket-powered version known as EF127, hoping that the more intuitive controls would be more to the community's liking.

(The following are Simple Universe story)

After setting up the OKB-1, the Soviets were able to get their hands on some of the most secret German late-WWII projects, especially those from Dr. Baade and his development team in Junkers aircraft. Post-war USSR is just as poor as late-war Germany, and it was only natural that they wanted the same thing: a cheap, miniature fighter. The EF-127 "Walli" was the answer from the OKB-1.

Performance:
about 2100km/h at sea level.
about 4.5 seconds to turn 360 @ 1500+km/h

Armament:
2x MG151/20 autocannons (70 damage, 12 rps, 805 m/s)

Activation Groups:
AG1 for takeoff booster (RATO rockets). The rockets provide 9 seconds of boost, would detach 10 seconds after ignition, and would self-destruct at 12 seconds after ignition.
AG2 for jettison takeoff carriage. Suggest dumping it in deep water to reduce random jerking phenomenon.

The lights in the cockpit are for AG1 (left) AG2 (right) and landing gear (middle). Note that landing gear action is reversed, so trust your light and don't trust the in-game landing gear tooltip.

For unknown and unsolvable reasons, this aircraft receives random roll impulses ("jerk") ever three seconds. The effect should gradually die out after a few minutes from takeoff, but there are some ways of reducing it. You can avoid extreme control surface inputs (which could magnify the jerks up to a sudden 120 degree roll), and try to jettison the carriage in water. For some reason they do help.
