Junkers EF.132 Flight Manual

Section I: Description

The Junkers EF.132 was a planned Luftwaffe project to build a high-speed jet bomber towards the end of WWII. Distinguished by its highly swept wings and tail surfaces, it was to carry up to 11,025 lbs of bombs and be powered by six 5,500 lb. thrust engines buried in the , giving it a top speed of 587 mph at 33,000’. It carried six 20mm cannon in three remotely-sighted defensive turrets, plus it may have also carried a forward firing armament of two additional cannon and featured an interesting landing gear arrangement. It never (thankfully) got off the ground, only reaching wind tunnel testing prior to the end of the war. Most of Junker’s efforts were carried off by the Soviet Union at the conclusion of the conflict and the design studies formed the basis for a number of Soviet experimental types and informed Soviet bombers such as the Myasishchev M-4 “Bison” and the Tupolev Tu-16 “Badger”. This is a 1 to 1 scale build with relatively accurate performance, weight and armament. It features bomb bay doors, rotating turrets and a bomb sight, sighted for drops from 30,000’ at 500 mph.

NOTE: This is a large, heavy jet which flies realistically, so it is a trim-intensive aircraft. Failure to take note of instructions pertaining to trim will lead to frustration!

Section II: Normal Procedures

Taxi & Takeoff:
1. Upon spawning, set brakes to stop bouncing and prevent rolling.
2. Activate AG1 for lights and nosewheel steering (as required).
3. Lower Flaps (AG1 + VTOL) (as required).
4. Set stab trim 1.5 units nose up [trim slider down 1 ½ notches].
5. Set full power (100%) for takeoff.
6. Maintain centerline w/small “stabs” of rudder, aircraft will rotate at 170 mph and liftoff at 210 mph.
7. Retract gear when clear of ground, trim forward to maintain pitch to climbout at 250 mph.

Climb:
1. Best rate of climb 250 – 300 mph, 10 – 15 degrees nose up.
2. Activate air-to-air mode to clear for air threats.

Level-Off and Cruise:
1. Set stab trim to .5 units nose up [trim slider down ½ notch], power as required for level flight.

Turret Control:
1. AG3 and VTOL to traverse the dorsal turret and activate guns, camera 2 for view.
2. AG4 and VTOL to traverse the tail turret, AG5 and VTOL for tail gun elevation and to activate tail guns, camera 3 for view.
3. AG6 and VTOL to traverse belly turret and activate guns, camera 4 for view.

Bombing:

NOTE: Bombsight is calibrated for 30,000’ above target and 500 mph airspeed. Recommend setting Initial Point (IP) for bomb run approximately 2 mins (8.3 miles) prior to release point.

1. Level off at 30,000’ and fly level at 500 mph (approximately 80% rpm). Aircraft will fly level at approx 2 – 2.5 degrees nose up with trim set approx .5 units nose up [trim ½ notch down].
2. Open bomb bay doors with AG2 and VTOL down.

CAUTION: Be sure to open bomb bay doors prior to releasing weapons, or weapons will “hang up” in the bay.

3. Switch to camera 1 for bombsight view, release weapons normally when target reaches center of crosshairs.
4. Close bomb bay doors at conclusion of bomb run. Follow first bomb with camera 5 view.

WARNING: Do not move slider up past halfway/neutral point on VTOL when closing bay doors, bombs not yet dropped may contact doors and explode.

Approach & Landing
1. Establish straight-in approach, configured with gear and flaps (as required).
2. Fly approach at 200 mph, approximately 50% rpm. Trim as required.
3. Over underrun (approximately 50 ft), cut power to idle and flare.
CAUTION: Aircraft will balloon in the flare. Take care to control pitch rate in flare.
WARNING: Hard touchdowns may result in structural failure, aircraft loss and loss of life.
4. Apply brakes as required.

Section VI: Flight Characteristics
This aircraft is a heavy jet and flies like a heavy jet. Fly this aircraft primarily with trim, use smooth control inputs and anticipate roll in and roll out. Approximately .5 units nose up trim [trim slider down ½ notch] is required for level flight.
WARNING: Aircraft may depart controlled flight if below 200 mph and abrupt back stick input is made. To recover, set full throttle, release back stick pressure, lower nose to gain airspeed and carefully recover from dive.

    @ChiChiWerx well, thats exactly what i thought about the wings. Although i would like try to retain the camo, it looks too good.

    I suppose, i will try using the wings of tu-104 (https://www.simpleplanes.com/a/1R09Kg/Tupolev-Tu-104A-1956-Update-2) , they are about right in form and dimensions. Will delete the inner flaps section and landing gear pods, add engines and remake the inner part. Anyway, tu-16/tu-104 wings were really based on ef132 research.

    @vonhubert no worries on time. I wanted to let the aftershocks from this build die down anyways, before posting a variation. I think what we can do is a night bomber version of this build. I wanted to tweak a few things as well, like the elevators, increase the wing sweep by about 5 degrees and make the three part wings (LE, center section and TE). Night camo would free us up from the camo thing, as most Luftwaffe night bombers were overall black with white markings. I would be sure to make the black a shade or two lighter than the darkest, that way it stands out against the background. What do you think?

    @ChiChiWerx Thanks, i pretty much know about xml modding, but never looked where are the color settings) About the turrets - its pretty simple:
    1) put the horisontal rotator to "roll", vertical to "pitch". For a vertical rotator XML edit the input to "0;1" if it is a turret above the fuselage or "-1;0" if below (so you dont shoot your plane", edit rotation limits also.
    2) make the controls for a plane activated with some AG so you can level the plane, lock the controls and use "mouse as joystick" to rotate turrets. Than it works exactly as mouse aim except p3-4
    3) XML mod all the turrets parts to 0.000001 weight to make em less shaky
    4) add camera with "autocenter" setting

    for landing gear doors - it is more difficult to explain. would be easier to show, look at my m-4 bomber. Landing gear door has a rotator that allow some free movement and the rotator that actually close the door, and a spring to hold em down. So it opens fast, but closes slow as it has to wait while the free rotating rotator reaches its limit.

    p.s. i can upload a turret assembly for you. or you can cannibalise my m-4 model for a concept. But it wont be perfect as the rear turret is different and a camera is set separate from the turret itself. front turrets. however seem pretty similiar. I actully made a better variant of m-4 where both front turrets are controlled simultaneously from a separate small cocpit.

    @vonhubert the gloss is XML modding. Access the XML files (thisPC/C:/Users/Your profile name/AppData/LocalLow/Jundroo/SimplePlanes/AircraftDesigns), open the corresponding folder and go to the color list, which is near the bottom of the file. Open the file you want using Notepad. Select the color you want to modify and set m = "1" and s = "1". The color list will be in the same order as in the custom color palette (left to right, top to bottom). You can also Google "hexcolor" to get color codes for any custom color you want to choose and substitute the listed color for the new color. Save the file, then you have to reload the aircraft in the editor to see the new color and gloss settings. As far as modding the plane, sure, have at it! I like the mouse controlled turrets idea, you'll have to tell me how to do that for my next build. As for the gear and door synchro, sure, sounds great. The wing Mod, well, I considered making them out of several big XML modded parts, but wouldn't have been able to carry the camo pattern over if I had done that.

    BTW, how did you get the canopy THAT gloss like a mirror?

    p.s. can i kindly ask a permission to make an update of your plane some time later? Your fuselage and painting is perfect, but i have an idea how to make better wings and landing gear with doors that open and close synchronized with gear itself + mouse controlled turrets.

    @Wildblueyonder578 are you starting on the ground? If you try and start in the air, say on Yeager final, you'll probably stall it trying to avoid the cliffs due to the slow engine acceleration and wing loading. BTW, like your avatar image, nice B-57.

    @Wildblueyonder578 what exactly do you mean? If you mean, it won't take off, then try to set 1.5 units nose up trim (slider down 1 1/2 notches). Aircraft should rotate around 170 mph and go airborne around 210 mph. That's all in the flight manual. If you mean, it flies "heavy", well...it should! It's 140,000 lbs and the flight characteristics are pure SP, no XML modding weights, CG or fuel.

    I reall do not want to sound rude, but I'm barely getting any lift from this bomber. Any ideas?

    @ChiChiWerx Agreed. Trim is the best way to build a plane that is stable over a wide range of speeds.
