摘要： Die Erfindung betrifft eine Antriebsvorrichtung (1) für ein Luftfahrzeug, die einen Rotor (2; 2b; 2c) mit einem Rotorgrundkörper (4-4c) und mit an dem Rotorgrundkörper (4-4c) angebrachten Rotorschaufeln (3; 3b; 3c) aufweist, wobei der Rotorgrundkörper (4-4c) und die Rotorschaufeln (3; 3b; 3c) von Luft umströmbar sind. Zweckmäßigerweise ist der Rotorgrundkörper (4-4c) rotationssymmetrisch ausgebildet. Eine Stromlinienverkleidung ist nicht erforderlich. Vorteilhaft wird dennoch sichergestellt, dass keine Strömungsverluste auftreten. Weiter vorteilhaft wird eine besonders einfach herzustellende Antriebseinrichtung geschaffen. Ferner betrifft die Erfindung ein Luftfahrzeug, insbesondere ein Flugzeug oder eine Drohne.

摘要： Methods and systems for starting propeller driven aircraft and other devices are disclosed. A system in accordance with one embodiment of the invention includes a removable fixture that is coupled to the propeller and has at least one portion exposed to a flowstream to rotate the propeller during engine start-up. The fixture is configured to separate from the propeller after the engine begins to turn over (e.g., after the engine starts and/or rotates above a threshold rate). Accordingly, the system can include a releasable link between the fixture and the propeller.

摘要： The jet engine for aircraft propulsion has a thrust nozzle which extends from the high temp. combustion chamber. For subsonic flight the combustion chamber is supplied with compressed air by a shaft-driven axial flow air compressor. In the modified engine the compressed' air is supplied by a number of free piston compressors (7a) which are arranged in a ring around a central combustion chamber (1) and thrust nozzle (4). The compressors (7a) are mounted in a housing (6) which can be rotated about the engine longitudinal axis to bring each compressor to the lowest position for ease of servicing. USE - Aircraft propulsion.

摘要： A turbocharged, compounded cycle ducted fan engine system includes a conventional internal combustion engine drivingly connected to a fan enclosed in a duct. The fan provides propulsive thrust by accelerating air through the duct and out an exhaust nozzle. A turbocharger is disposed in the duct and out an exhaust nozzle. A turbocharger is disposed in the duct and receives a portion of the air compressed by the fan. The turbocharger compressor further pressurizes the air and directs it to the internal combustion engine where it is burned and exits as exhaust gas to drive the turbine. A power turbine also driven by exhaust gas is also drivingly connected through the engine to the fan to provide additional power. The size and weight of the turbocharger are reduced since the compressor's work is partially achieved by the compression effect of the fan. The total propulsive thrust includes the fan generated thrust which bypasses the turbocharger and the thrust of exhaust gases exiting the turbine.
