Variable Geometry Configuration Testbed

The Variable Geometry Configuration Testbed, internally codenamed 9P003, was developed entirely independently by Kebal Central Institute of Aerohydrodynamics, the largest aircraft manufacturer in South Kerbin. It was the first successful twin-engine heavy variable geometry vehicle on the planet. Its complex and sophisticated variable sweepback system draws all its technical expertise from the legendary 9P002A1 testbed and the Object 728 "Gemini".

The program faced several challenges back in the days it was initiated. One critical technical problem was that the wings wobble under large G forces was almost impossible to suppress. Through countless redesigns and test flights, genius engineer BunnyFenger UwU eventually figured out a way to get the leading edge of the wings to cut the airflow at an angle of almost 90 degrees to eliminate wobbling.

The prototype was built to study the feasibility and practicality of variable geometry technology on Kerbin. Studies have shown that this configuration is achievable, but impractical, because the aircraft can only withstand G forces when the wings are folded, at which the drag will be counterintuitively increased.

*This aircraft is equipped with the Maneuver Load Alleviation System (MLAS), but it's hidden by default. To enable it, just simply enable pitch control of the outboard ailerons.

Note: The MLAS has a speed limit of 260m/s when wings are not folded. When wings are folded, the actuators must be adjusted to -30 degrees or disabled, otherwise the warranty is void.

23/08/2024 update: The MLAS is now automatic, but if the pilot decides to use key 3 in any circumstances, they need to keep an eye on the wings. When a failure occurs, disable the system manually.
