WS-25 Sea Slug Seaplane

Entry for WinsWing Seaplanes Rebuild Challenge

Background

The year is 1950s, and a lot of things happened after the war. Many technological progress was boosted by the war effort, and one of them was the invention of the jet engine. In this particular situation, the jet engine that still used a propeller—turbo propeller—was on the rise.
The prominent use of seaplanes in WW2 was an interesting strategy to open the versatility of aircraft, using the whole ocean as a takeoff and landing ground. But as the year progressed after the war, the use of seaplanes was dwindling down. Given that some fleets of seaplane that we have, we made an effort to make the seaplanes stay relevant by combining both seaplanes and new turbopropeller engines to potentially improve their speed, MTOW, and overall versatility of the aircraft.

Design and Description

W-25 Sea Slug is a two-seat, dual-engine seaplane aircraft intended to guard naval ports. The design itself was very WW2 era styled, given that it was based on the WW2 era seaplanes. The use of a turbopropeller with a contrapropeller engine was the first of its kind as the combat theatre of the era become apparent for need of high speed high performance aircraft. The engine also increased the payload capacity of the aircraft, noting its ability to carry rockets and 75mm gun, heavy for its size.

Although the initial design was for a medium seaplane bomber, the aircraft was very versatile, noting the similar all-around capability of the British de Haviland Mosquito. The multiroleness of this aircraft led to their adoption for navy bombing wing, navy port defend wing, and also coast guard.

Role

• Port Defense
• Attacker
• Medium Bomber
• Search and Rescue (Coast Guard)
• ASW (concept)

Armament

• 2 x 20mm Defensive Cannon
• 1 x 75mm Offensive Cannon
• 4 x ASR-35 ''Auklet'' Waterburst Rocket

Features:

- Simulated Water Drag

I put some jet engine that simulate the drag when moving in water according to aircraft movement.

Control:

Control:
AG1 : Light
AG2 : Airbrake
AG3 : Master Arm (rocket)
AG5: Jettison
AG8: Canopy

Takeoff (Both Water and Runway)
1. Full Flap, Half Trim, and Throttle
2. Let the aircraft speed up; no pitch input needed. Adjust roll for any autoroll
3. After aircraft is airborne, immediately Flaps off (VTOL=0)
4. Let the aircraft gain speed, adjust pitch, preferably using trim.
5. The aircraft is at its most stable flight at speed of 350kmh+

Runway Landing
1. Throttle 30-40%, half Flaps, Airbrake
2. Adjust pitch, preferably using Trim. (Personaly i feel half trim works best)
3. When touching down, brake release brake release until the speed below 100kmh then fullbrake
4. Smite anything in the vicinity using twin 20mm until God of Blood satisfied

Water Landing
1. Water landing is easier. Any method that results in the belly touching the water is sufficient.
Beware of the waterburst rocket; any hard contact with water would explode the rocket to explode.

Weapon Briefing:

- ASR-35 ''Auklet'' Waterburst Rocket

Waterburst Rocket made by AWESOMENESS360. Explode on contact of water. Quoted from post: "function best when firing them at any altitude between 300-1,000ft, at angles no more than 30°, otherwise they have a chance of not detonating properly"

Specification
Mass: 133 kg

- 75mm Offensive Cannon

75mm Artilery taken from anti-tank cannon, modified with autoloading mechanism.

Specification

Muzzle Velocity: 1050 m/s
Ammo: 10 rounds

- 20mm Defensive Cannon

20mm to shoot back at someone. Good for defensive or straffing/gunship.

Specification
Caliber: 20mm
Muzzle Velocity: 1050 m/s

Note

• Feel free to take the missile
• I use high physics when building this so use the same setting
• If your device cannot run this, try to set every quality setting to low
• If you use laptop, I suggest charging ur laptop while running this aircraft. In my experience, my laptop could run higher part count smoother while being charged.

Author note

I might slow down a little. Mainly cuz life, and I think I start to lose interest of this game again. We will see.
I don't like making slow aircraft. They fly so slow, any bug was really slow to notice. Fast forward was not helping
But making slow aircraft doesn't need any complex code for glimit. So that some win.

anyway, enjoy.
