motorjet engine

Motorjet engines provide greater thrust than a propeller alone mounted on a piston engine; this has been successfully demonstrated in a number of different aircraft.

Japanese engineers developed the Tsu-11 motorjet engine to power Ohka aircraft as an alternative to the solid-fuel rocket engines that these aircraft were then using.

Decades later, after the practical demonstration of motorjets and turbojets, Coandă began to tell various conflicting stories about how his early experiments were precursors to the jet, even that his turbo-propulseur was the first motorjet engine complete with fuel combustion in the air stream.
