Japanese Army Type 99 Twin-engined Light Bomber that was used during World War II.
Design and Structure
Type: Twin-engined Light Bomber
Wings:
- Configuration: Mid-wing cantilever monoplane with straight taper on both leading and trailing edges and dihedral from the roots.
- Structure: Made of metal, featuring flaps between the fuselage and engine nacelles, as well as between the nacelles and ailerons. The ailerons are fabric-covered. Landing lights are positioned in the leading edge of both wings, and there is a small fillet on the trailing-edge roots.
Fuselage:
- Construction: A deep metal structure extending to the aft of the trailing-edge, with a slender rear section. The covering is made of metal. The bomb stowage is located in the center-section.
Tail Unit:
- Type: High cantilever tailplane with a metal covering, fabric-covered elevators, a single metal fin, and a fabric-covered rudder. Trim-tabs on the rudder and elevators are metal.
Landing Gear:
- Configuration: Retractable backwards into the engine nacelles, leaving part of each wheel exposed. The tail-wheel is semi-retractable.
Power Plant
- Engines: Two Nakajima Type 2 (Ha 115) fourteen-cylinder radial air-cooled engines, each producing 1,150 hp.
- Nacelles: Underslung nacelles extend to the trailing-edge, equipped with controllable cooling gills.
