The Morane-Saulnier TRK (aka Morane-Saulnier MoS-9) was a prototype French bomber built during World War I.


The Morane-Saulnier TRK was a large triplane with the engines mounted in the fuselage, facing outboard and canted upwards. The engines drove a propeller each, through driveshafts and bevel gearboxes, with the propeller gearboxes strut mounted beneath the middle mainplanes. Cooling for the engines was provided by a tall radiator stack above the centre of the fuselage, between the middle and upper mainplanes. The two tractor propellers ran just forward of the middle mainplanes.[1]

Two pilots sat in open cockpits side-by-side in the nose of the aircraft, which also had a wind-driven generator at the very tip. The third crew-member was housed in the rear fuselage and attended the engines in flight or operated defensive armament. The fixed undercarriage was of the conventional contemporary tail-skid type, with a nose-over protection wheel, strut-mounted under the nose. The left and right, strut-supported, mainwheel assemblies were of very wide track, with a wheel at each end of both axles.[1]
