Abstract: A steam engine (10) has an engine case (14), a stator (20) with a radially-inner surface (52) with a plurality of recesses (54), a steam generator (12) and a rotor 5 (22) that has a steam distribution chamber (44) arranged to receive steam from the generator and a plurality of steam distribution channels (46) having outlets (50) for the flow of steam into the stator recesses (54). The rotor has pressure relief ports (60) for the flow of steam from the recesses (54) into the engine case (14) and then to a condensation circuit (66). The engine operates without a boiler and produces 0 steam by injecting water into the generator (12) where it is rapidly vapourized. The rotor (22) is the only moving part and the engine can produce a wide range of power outputs.

Abstract: A simple, safe, and inexpensive flight control system in an aircraft. An anti-torque system for a rotary-wing aircraft has an airfoil with a first surface extending from a first trailing edge and a leading edge, and a second surface extending from a second trailing edge to join the first surface at the leading edge. The airfoil has a first moveable deflector panel pivotally coupled to the first trailing edge, and a second moveable deflector panel pivotally coupled to the second trailing edge. Means are provided to pivot the deflector panels in unison about their respective pivot axes to alter the direction of travel of the airflow downstream of the pivot axes over the surfaces of the deflector panels, thereby producing a lift in a direction perpendicular to the airflow to counteract the torque applied on the aircraft. The flight control system may be arranged within a fixed-wing aircraft.
