The '''Messerschmitt Me 509''' was a project underway in [[Germany]] during [[World War II]] based on the [[Messerschmitt Me 309]] but with the engine located behind the cockpit like the US [[Bell Aircraft Company|Bell]] [[P-39 Airacobra]].
The engine was a [[Daimler-Benz DB 605]]B driving a three-bladed [[propeller]] and armament was to consist of two 13 mm [[MG 131 machine gun]]s and two 20 mm [[MG 151 cannon]]s. The [[Undercarriage|tricycle landing gear]] from the Me 309 was retained, which worked better on the 509 due to the lower weight on the nosewheel - the Me 309's front landing gear had collapsed during trials. Visibility was also better with the smaller nose. The project was cancelled along with the Me 309, but the [[Japan]]ese made a similar aircraft, the [[Yokosuka R2Y]] Keiun, which suffered engine overheating, a problem that may have faced the Me 509, but the design may have been influenced by the Me 509.

The Messerschmitt Me 509 was an all-metal fighter project, underway in Germany during World War II.

Development

[edit]

Not much information about this project has survived. It was based on the Me 309 but with the engine located behind a pressurized cockpit, much in a similar manner to the US Bell P-39 Airacobra.

The engine was a Daimler-Benz DB 605B driving a three-blade propeller, and armament was to consist of two 13 mm (.51 in) MG 131 machine guns and two 20 mm MG 151/20 cannon. The tricycle landing gear from the Me 309 was retained, which worked better on the 509, due to the lower weight on the nosewheel - the Me 309's nosegear had collapsed during trials. The smaller nose would have improved visibility. The project was cancelled along with the Me 309,[1] but the Japanese made a similar aircraft, the Yokosuka R2Y Keiun, which suffered from engine overheating.[2]
