专利汇可以提供Method for reducing drag of vertical takeoff type aircraft专利检索,专利查询,专利分析的服务。并且Method of reducing drag on an aircraft of the vertical takeoff variety and having a particular power plant for production of vertical thrust as well as a main engine for producing forward thrust during aerodynamic flight; the vertical thrust producing power plant is used as power source for controlling the boundary layer flow along at least part of the surface of the aircraft during aerodynamic flight, residual thrust of that plant is deflected to contribute to forward thrust, supplementing the forward thrust produced by the main engine.,下面是Method for reducing drag of vertical takeoff type aircraft专利的具体信息内容。

1. Method of reducing drag of an aircraft of the vertical takeoff variety and having main engine means for producing forward thrust during aerodynamic flight and having a power plant, separately from the main engine means, for production of vertical thrust, comprising the steps of using an ejector pump for extracting suction power from the vertical thrust producing power plant; controlling the boundary layer flow along at least part of the surface of the aircraft during aerodynamic flight, without affecting the main engine means, by using the suction power as extracted by the ejector pump for sucking air through said surface part; and providing concurrently exhaust jet deflection in the vertical thrust providing power plant to contribute to forward thrust by supplementing the forward thrust provided by the main engine means.
