The ducted fan has a different operating behavior from the free propeller. In particular, when high blade numbers are used, e.g., for noise reduction, it is difficult to incorporate a blade pitch control mechanism. This complicates the matching of a combustion engine and the fan: During crui...
A turbojet of the unducted rotor type and an aircraft including such a turbojet, the turbojet including a gas generator, a first unducted propeller connected to a shaft of the gas g
According to the present invention, there is provided a vehicle, comprising: a fuselage having a longitudinal axis and a transverse axis; at least one lift-producing propeller carried by the fuselage on each side of the transverse axis; a pilot's compartment formed in the fuselage between the ...
similar size to its predecessor, but has a pusher propeller along with its rotor and can be fitted to a configuration with wings for long-range reconnaissance missions. Other than the electric-motor-tethered AROD built by Dr. Moller, all past VTOLs, manned or unmanned, have used fuel-...
Based on the vortex theory and thin airfoil method,an engineering-oriented method for the ducted-propeller anti-torque system was investigated,included the airfoil shaped ducted body,propeller and the central body modelling technology. 分别采用涡流理论、面元—薄翼型和源—汇模型的组合建模方法建立了包...
It is usually used as a lifting device in aircrafts because of its high efficiency and high safety, but the interaction between duct and propeller cause a great difficulty in calculating ducted propeller aerodynamic characteristics. 涵道螺旋桨是涵道和螺旋桨的组合体,其气动效率高、安全性能好,常用作...
