Kawasaki Ha-40 Engine
| Ha-40 | |
|---|---|
| |
| Preserved Daimler-Benz DB 601. | |
| Type | Piston V12 aircraft engine |
| National origin | Japan |
| Manufacturer | Kawasaki |
| First run | 1930s |
| Major applications | Kawasaki Ki-61 |
| Developed from | Daimler-Benz DB 601 |
The Kawasaki Ha-40 was a license-built Daimler-Benz DB 601A-1 12-cylinder liquid-cooled inverted-vee[1] aircraft engine selected by the Imperial Japanese Army Air Service (IJAAS) to power its Kawasaki Ki-61 Hien (Allied reporting name[2] "Tony") fighter.
Design and development
The Daimler-Benz DB 601A-1 was a development of the earlier DB 600, with direct fuel injection replacing the carburetor. Like all DB 601s, it had a 33.9 litre displacement. The first prototype with the direct fuel injection was test run in 1935, and an order for 150 engines was placed in February 1937.
A second manufacturing license was granted to Aichi, for production of the same engine for the IJN as the Atsuta. The Atsuta powered only two models of Imperial Japanese Navy Air Service (IJNAS) aircraft aircraft in World War II. The IJNAS's Atsuta and its IJAAS "cousin", the Ha-40 were based on the engine that powered Germany's Messerschmitt Bf 109 fighter.[3]
A new high-horsepower engine was required for the Kawasaki Ki-64 experimental fighter. The aircraft design called for a narrow profile fuselage, and the solution that Kawasaki developed was the Ha-201 engine. This engine was a compound engine where two Kawasaki Ha-40 engines were connected to a common gearbox that was mounted in the nose. The gearbox drove a pair of three-blade contra-rotating propellers. Although similar to the Aitchi Ha-70, where two Aichi Atsuta engines were mounted side-by-side, this arrangement called for the engines to be separately mounted, one in the aircraft's nose, the other behind the cockpit. The rear engine was connected to the nose mounted gearbox by a drive shaft.
Variants
- Ha-40
- Up to 1,175 PS (864 kW) at sea-level with 2,500 rpm, up to 1,100 PS (809 kW) at 2,400 rpm and 3.7 km altitude.
- Ha-201
- Two Ha-40 coupled together with a gearbox to drive a twin three-blade contra-rotating propeller for use in the Kawasaki Ki-64. The combination was rated at 2350 hp.
Applications
- Ha-40
- Ha-201
