This is a dive bomber on USS Bunker Hill cv-17.

Zeus dive bomber

She was the nemesis of the fascist army in the Pacific.

Like Zeus splitting lightning from the sky,

She came down from the sky, with fierce dive, lightning like bombs, thunder like roar and accurate destruction of the enemy.

A dive attack from the direction of the sun smashed the backbone (keel) of the enemy fleet

Zeus dive bomber / Fighter (virtual background)

This excellent dive bomber was developed in 1938,

At that time, the dive bombers were usually two seater, but the designers of Zeus took a new approach and made the first single seater dive bomber in the world at that time, reducing one member, making the aircraft body more compact, smoother, with less resistance, lighter structure, able to mount more and heavier ammunition, relying on their own faster speed and more flexible mobility without relying on it Rear gunner to counter the enemy's attack.

Such a design is more similar to the concept of attack aircraft in the late WW2 and early cold war. It is a kind of advanced design.

Of course, such a design also makes the only pilot more burdensome, which is not conducive to searching for targets and observing the enemy's situation in the vast sea. After all, it reduces one observer.

Like Vought F4U corsair, it uses an r2800 wind-cooled star engine. 2000hp gives her agile speed and outstanding mounting ability. The dive and projectile throwing hanger in the belly of the aircraft gives her the ability of 90 ° vertical dive and precise projectile throwing that few aircraft can achieve.

After replacing the dive hanger in the middle of the fuselage, it can mount a 907kg aviation torpedo at the center line as a torpedo aircraft.

Zeus without bombs can be used as an agile fighter, and the aircraft after dropping bombs can quickly change roles and become escort fighters for partners who have not yet dropped bombs. This is very helpful to simplify the aircraft types on the aircraft carrier.

The well-designed wings and control surfaces make the aircraft easy to navigate, allowing pilots of all levels to take off and land on the aircraft carrier easily.

(I want to build a 1938-1940 dive bomber / fighter, whose shape and flying quality are as realistic as possible. So we did this design, which is similar to the fw190 type of combat / attack / bomber. But more focused on attack / bombing missions than fw190. For this purpose, the speed reducer is specially installed. )

Control

VTOL down = flaps down

VTOL up = please do not use it, it will make the aircraft fall quickly

Trim= balancing

AG1 = turn on the wing (large) final drive (can slow down quickly and greatly increase the aiming time)

Ag2 = open the tail (small) auxiliary deceleration board of the aircraft (it is very convenient when the speed needs to be reduced slightly, so that the speed will not fall too fast, causing the aircraft to fall, but also to some extent, increasing the stability. Very suitable for landing and attacking targets)

Ag3 = launching of dive bomb hanger (to prevent the aircraft from hitting the propeller during large angle dive bombing)

AG4 = wing mounted (bomb) drop

Ag5 empty (can be arranged by yourself)

AG6 = turn on the compass route adjustment switch (after turning on, pull "trim", adjust the two dotted lines in the middle of the compass to identify the route)

Ag7 = landing hook

AG8 = fold the wings and turn off the artificial horizon and warning lights at the same time

The engine radiator will automatically control the opening angle with the change of throttle and flight speed, which is conducive to automatic heat dissipation.

In order to quickly pull up the aircraft when diving to low altitude, the designer has set up a flap with a very large lifting moment, and carefully adjusted the center of gravity of the aircraft. Normal takeoff and landing only need to open the flap to 1 / 4 gear. Only when the aircraft needs to be pulled up quickly, the flaps need to be opened for more than 1 / 2 of the gear. The combination of flap (open) and trim (trim) can keep the plane level flying controllable at low speed (140mph, 225kph).

When landing, thanks to the solid two wheel landing gear, landing is very convenient, but we still need to avoid too fast descent speed.

Simplify the number of parts as much as possible. The number of parts of the whole aircraft is controlled at 688. In addition, the number of dive bombing pylons is 722 in total.

In order to facilitate the operation on the mobile phone, many parts are simplified, and only the necessary large load hanging rack is left. Like to continue to mount weapons friends, you can continue to add your favorite wing mount and weapons.

Feature description

1. Learn the shape design of several aircraft, including F6F fighter, F4U fighter, f8f fighter, SBD bomber and P47 fighter.

Make the surface as smooth as possible, no obvious gap, and reasonable design.

2. Referring to historical photos and my own ideas, a cockpit with full instruments is built. Because it is a U.S. Navy aircraft, it uses imperial units (MPH and FT).

(in the earliest version, I built a "sideslip indicator" instrument, which performed perfectly in the ground test, but in the air maneuver, there would be a failure and loss of the indicator ball, so I had to remove this instrument, which is a pity.)


According to the order from top to bottom, from left to right, explain the instrument:

1. Dive height indicator
   Each scale represents an altitude of 500ft, starting from 6000ft.
2. Reflection sight
3. Two warning indicators.
   One is when the height is less than 300ft (91m) and the landing gear is not down, the light flashes to give a warning.
   One is the warning that the speed is lower than 103.57 mph (90 knots) (level flight cannot be guaranteed under this speed in case of heavy load)
4. Ag1-4 switch indicator light
5. Altitude meter (on the left side of artificial horizon)
   Unit ft. There are ten scales and three pointers in total. The white pointer indicates the ten thousand digit value, the red pointer indicates the one thousand digit value, and the green pointer indicates the one hundred digit value.
   (it is convenient to read out more accurate degrees, for example, the figure below is 3670ft)
   
6. Artificial horizon (equipped with a sideslip indicator)
7. Airspeed meter. (on the right side of artificial horizon)
   Unit mph. There are ten scales and four pointers,
   IAS in red
   White needle display TAS
   Refer to the actual two speed airspeed meter.
   A short, thick pointer indicates a hundred digit value, and a long, thin pointer indicates a ten digit value.
   (it is convenient to read out more accurate degrees, for example, the figure below is TAS 172mph,IAS 149mph)
   
8. Ag5-8 switch indicator light
9. Flap and tail trim angle indication
10. Falling rate meter
    Unit: ft / min. There are twelve scales, each of which is 500ft / min.
    (the speed is so low that it will be inaccurate when there is a big difference between nose pointing and motion vector)
11. Vertical attitude indication.
12. Horizontal attitude indication.
13. compass.
    The red and blue pointer indicates the north-south direction, and the yellow light indicates the orientation of the machine.
    Compass route adjustment: AG6, use trim to adjust the two dotted lines in the middle of the compass to mark the route (such as the airport azimuth).
    (at present, the compass and attitude indication are slightly defective, and will automatically turn around from the other side when turning 180 °)
14. Engine speed meter (in fact, throttle indicator)
15. Engine start switch and indicator light
16. clock. (only 12 minutes)
17. Up rate instrument
    Unit: ft / min. There are twelve scales, each of which is 500ft / min. (not very accurate)
18. AG1 switch and red indicator light
    For opening wing final drive
19. Ag2 switch and green indicator light.
    Used to open the auxiliary reduction board at the rear of the aircraft
20. Fuel gauge
21. Radio speaker
22. Green indicator light and landing gear switch
23. Height indicator.
    Run from 2400ft, count back to zero
24. Aircraft relative energy meter
    Relative gravitational potential energy + kinetic energy (regardless of aircraft mass, not brought into aircraft weight calculation)
25. Ag3 switch, the aircraft belly dive bomb drop rack is deployed for bomb drop (this switch is always on after it is turned on, and it will not be restored with the Ag3 button turned off, so that the driver can see that the bomb has been dropped and the rack is empty.)
26. The AG4 switch and the wing hanger drop bombs (the switch remains on after it is turned on, and will not be restored with the Ag4 button turned off, so that the driver can see that the bombs have been dropped and the hanger is empty.)
27. Oil tank selection knob
28. Engine thermometer (for accelerator and air speed)
29. Air inlet pressure gauge
30. Radio station
    Then we will introduce the devices on both sides of the driving bulkhead:
    
    On the left bulkhead are the throttle lever and the associated valve lever.

At the front left is the flap retraction and tail trim console (two knobs control trim and VTOL respectively)

There are two manual control wheels on the left side of the seat, which are used for manual flap retraction and balance as the manual backup in case of electrical failure.

There is a large diameter manual control wheel on the right side of the seat, which is used for the manual retraction and retraction of the landing gear

There is a control panel on the right front of the cockpit, on which all switches of ag1-ag8 are set.

The driving operating lever in the middle is equipped with a machine gun shooting trigger (located in the front of the operating lever in the middle, and the shooting is buttoned down) and a projectile dropping button (located on the top left side of the operating lever, yellow circle, and the projectile is pushed down).

You can even turn off the UI and rely on the cockpit instruments to control the aircraft's take-off, landing, flight and attack.I feel very interesting in this way. Welcome to try

3. realistic wing shape and area,realistic aircraft size and weight,realistic fuel quantity,Airfoil and landing gear doors

Wing built with wing cover,The wing, which is made up of a piece of wing cover, can show the effect of a part of wing cover breaking in battle

Landing gear module

(although the width of the system wing is reduced by 2-4 times, when you restore the wing area, you will find that it is still in the original position)
Reference to historical aircraft:

Sbd-5 Dive bomber
wing area: 30.19 M2
Empty weight: 6404 lb (2905 kg)
Load: 9359 lb (4245 kg)
Maximum takeoff weight: 10700 lb (4853 kg)

F6f-5 Fighter
wing area: 31m2
Empty weight: 3226 kg
Maximum takeoff weight: 15415 lbs (6990 kg)
Fuel capacity: 250 gallons (946 liters) of internal oil, up to 3×150 gallons (568 liters) of attached oil

"Zeus" Dive bomber/Fighter
wing area: 26.7m2 (excluding vertical and horizontal tail areas)
Empty weight : 9408lbs (4267kg) (including 1000LBS of an-m65 bomb, machine gun and ammunition weight)
Load capacity: 11478lbs (5206kg) (1 an-m65 1000LBS + 4×250lbs)
Fuel capacity: 309 gallons (1168 liters) of internal oil

True flap aerodynamic (when you lower the flap, it increases lift, not drag)

There is also a strong deceleration plate. When you dive, turn on the deceleration plate and keep 50-30% of the throttle (trim your plane with trim), and you will get a stable dive bombing platform that can keep the speed below 250mph (give you enough time to aim).

(attached)

The dive angle commonly used by pilots is 75 ° - 85 ° (this aircraft can reach 90 °), because this is a single dive bomber, which means that there is no backseat personnel to report the height loudly to remind the pilot of the time of dropping, so a dive drop altimeter is set on the side of the sight, with 12 scales in total, each scale is 500ft. Starting from 6000ft above sea level, the pointer rotates. At this time, you adjust the pointer to aim at the target. When the red pointer rotates 180 ° (12 o'clock position) to 3000ft above sea level, you need to be ready to drop bombs. When the red pointer is turned to 270 degrees (9 o'clock position) to 1500 feet above sea level, it is necessary to drop the bomb and exit the dive, maintain the safe height, and avoid the collision caused by the low remaining height, which is a warning height.

Please pull up your plane at a safe distance

1. Flap to maximum angle;

2. Stow the speed brake;

3. Pull back the control lever with force, increase the throttle, operate the elevator, exit the dive and maintain the height.

At this time, there will be a loud explosion of the target being hit behind you. Accompanied by the rising fireball, the brave pilot returns triumphantly.

4. Refer to historical materials and movie pictures to make dive bomb hanger

Historically, professional dive bombers have been able to drop bombs accurately at a large angle of more than 70 °. Special hangers can throw bombs out of the propeller's blade radius (to avoid hitting the propeller), while maintaining the bomb's attitude (to ensure accuracy).

We've also installed this professional drop tool (basically the same as the SBD dive bomber)

(attached)

(the front part of the bomb rack is hinged with the fuselage, and the rear part is connected with the bomb. When the bomb is dropped, the bomb leaves the fuselage and is connected with the bomb rack. The bomb rack rotates forward and downward until it is 90 ° with the fuselage, so that the bomb leaving the rack avoids the propeller.)

It can ensure that our aircraft can achieve 85 ° ~ 90 ° vertical dive bombing, which is extremely accurate.

Of course, the pilot needs training to adapt to the feeling of the land coming from the flying face and aim accurately.

5. The reflection collimator is made of reference photos and games.

In the process of manipulation, there will be line of sight swing. During the swing, it can still keep its sight and hit the target.


Set the front and rear aiming fields, and press the field of view switch button to switch.

A simple third person perspective is also set up to track the movement of the aircraft. Quasi star is a small red bright spot, a little similar to the visual experience of air combat games.

6.Try to get closer to the real weapon

The front firing weapon is 8× 0.50 in (12.7 mm) M2 Machine Gun
AN-M65 Aerial bomb(1000lb)
(In order to simplify the parts, the tail of the bomb is a little simplified)
The HP of the engine body is adjusted to reflect the real weakness (radiator, engine room).

7. Simulate jitter during driving

8. The painting color refers to the American Navy Aviation painting in history, but it is slightly different.

Two color coating of reference SBD dive bomber

Use the logo of USS Bunker Hill cv-17 (white arrow ?)

(This painting shows the F4U fighter flying over Iwo Jima. The white arrows on the vertical tail and right main wing indicate that it belongs to USS Bunker Hill cv-17. In early 1945, the aircraft on USS Bunker Hill cv-17 briefly painted its nose yellow, but it was soon cancelled.)

(The F6F features a single color finish and a simplified white logo.)

9. Bias towards true engine characteristics

The engine is set to take-off power of 2200 HP (convenient for taking off from the shorter runway of the aircraft carrier), and the maximum power after the landing gear is folded is 2000 HP.

Because it's an attack aircraft at sea.

It optimizes the middle and low altitude performance and discards certain high altitude performance.

The power of the engine will decrease with the increase of altitude, and the higher the altitude, the greater the power attenuation. The supercharger will be opened at altitude of 11480ft (3500m) and 21325ft (6500m), and each supercharger will use 2.5% of the engine power.

These functions are implemented through funky trees version 1.9.

This formula is used:
1.1Throttle(1-AltitudeAltitude/200000000)+(-LandingGear)Throttle0.1+clamp(Altitude - 3000,Throttle-0.025,Throttle0)+clamp(Altitude - 6000,Throttle-0.025,Throttle*0)

ps:

landing gear retracted in advance:

in order to make the gear cover and the body tight. I put the landing gear in the wing ahead of time. When you enter the game, the landing gear will automatically expand.
