hello guys i did a cool nazi prototype i did it bcz i really liked it so i did it and its also mobile friendly anyways heres some histriy about it:

Lippisch P.13a

Overview

The Lippisch P.13a was a late–World War II experimental interceptor project designed in Germany under the leadership of Alexander Lippisch, a pioneer of delta-wing aircraft. Unlike most aircraft of the time, it was envisioned as a tailless, ramjet-powered fighter with a radical delta-wing layout.

The design stood out not only for its futuristic shape but also for its proposed fuel source: powdered coal. This made it unique among aircraft projects of the 1940s.

Development
• 1942–1943: Lippisch was already experimenting with delta-wing gliders and early jet designs (like the DFS 194, which led to the Messerschmitt Me 163 Komet). His work with tailless designs naturally led to the P.13a concept.
• 1944: As Germany’s fuel supplies became critically low, engineers began investigating alternative power sources. The P.13a was proposed to run on lignite (brown coal) powder, which could be burned in a special ramjet engine.
• Ramjet Principle: The P.13a would not use a conventional takeoff. It required an auxiliary rocket booster or tow-launch to get airborne and accelerate to the speeds necessary for its ramjet to ignite.

Design Features
• Tailless Delta Wing: Provided stability at high speeds, resembling designs that would influence later supersonic jets.
• Ramjet Engine: Occupied the nose section, with air intake at the front and exhaust at the rear.
• Coal Fuel: A rotating drum inside the engine was intended to burn powdered coal mixed with air, making it a desperate but innovative solution to fuel shortages.
• Armament: Planned to carry a single heavy cannon (likely a 30 mm or larger) for bomber interception.

Testing
• Wind Tunnel Models: Several scale models of the P.13a were built and tested in wind tunnels to validate the aerodynamics of its radical shape.
• Glider Prototype: A full-scale, unpowered glider version was constructed (the DM-1), but it was not completed before the war ended. The Allies captured it and sent it to the U.S. for study.

Fate & Legacy

The P.13a never flew under power. With Germany’s defeat in 1945, the project ended before the ramjet system could be tested in practice. However, the aerodynamic data gathered from the P.13a and the DM-1 glider significantly influenced post-war delta-wing research in both the United States and the Soviet Union.

Many historians see the Lippisch P.13a as a visionary but impractical design — ahead of its time in aerodynamics, but undermined by the desperate coal-powered ramjet concept. Still, its delta-wing layout foreshadowed successful aircraft such as the Convair F-102, Dassault Mirage series, and even modern stealth deltas.
