Abstract:
본 기술은 드론에 관한 것으로, 더욱 상세하게는 압축기체를 분사하여 비행되는 드론에 관한 것이다. 일 실시 예에서, 터보 제트 드론이 개시(disclosure)된다. 터보 제트 드론은 외부의 기체를 흡입하여 배출하는 엔진부를 포함한다. 상기 엔진부에서 배출되는 기체가 압축되어 외부로 배출되는 추진부를 포함한다. 상기 엔진부에서 배출되는 기체가 압축되어 선택적으로 외부로 배출되는 터보추진부를 포함한다. 본 명세서에서 개시하는 터보 제트 드론은 터보추진부에 의해서 추진부와 다른 추가 추진력이 제공됨으로써 비행출력이 향상될 수 있다. 그리고 터보조절부에 의해서 터보배출부의 크기가 조절되어 추가 추진력의 강약이 제어되는바, 터보 제트 드론의 방향을 제어할 수 있다. 또한, 하나 이상의 팬이 중첩된 터보제트팬을 포함하는 엔진부에 의해서 더욱 강한 공기를 배출할 수 있어서, 비행출력이 더욱 향상될 수 있다.
Abstract:
A propulsion system coupled to a vehicle. The system includes an ejector having an outlet structure out of which propulsive fluid flows at a predetermined adjustable velocity. A control surface having a leading edge is located directly downstream of the outlet structure such that propulsive fluid from the ejector flows over the control surface.
Abstract:
A propulsion system coupled to a vehicle. The system includes a convex surface, a diffusing structure coupled to the convex surface, and at least one conduit coupled to the convex surface. The conduit is configured to introduce to the convex surface a primary fluid produced by the vehicle. The system further includes an intake structure coupled to the convex surface and configured to introduce to the diffusing structure a secondary fluid accessible to the vehicle. The diffusing structure comprises a terminal end configured to provide egress from the system for the introduced primary fluid and secondary fluid.
Abstract:
A vehicle includes a main body and a gas generator producing a gas stream. At least one fore conduit and tail conduit are fluidly coupled to the generator. First and second fore ejectors are fluidly coupled to the at least one fore conduit. At least one tail ejector is fluidly coupled to the at least one tail conduit. The fore ejectors respectively include an outlet structure out of which gas from the at least one fore conduit flows. The at least one tail ejector includes an outlet structure out of which gas from the at least one tail conduit flows. First and second primary airfoil elements have leading edges respectively located directly downstream of the first and second fore ejectors. At least one secondary airfoil element has a leading edge located directly downstream of the outlet structure of the at least one tail ejector.
Abstract:
A homeostatic flying hovercraft preferably utilizes at least two pairs of counter-rotating ducted fans to generate lift like a hovercraft and utilizes a homeostatic hover control system to create a flying craft that is easily controlled. The homeostatic hover control system provides true homeostasis of the craft with a true fly-by-wire flight control and control-by-wire system control.
Abstract:
A plated polymer component is disclosed. The plated polymer component may comprise a polymer support, a metal plating deposited on a surface of the polymer support, and at least one flame-retardant additive included in the polymer support. In another aspect, the plated polymer component may comprise a polymer substrate, a metal plating deposited on a surface of the polymer substrate, and a temperature-indicating coating applied to at least one of a surface of the metal plating and a surface of the polymer substrate.

A composite component and a plated polymer component are disclosed. The composite component may comprise a body portion formed from an organic matrix composite, a first metal coating applied to a surface of the body portion, and an outer metal layer on the first metal coating that is erosion-resistant. The plated polymer component may comprise a polymer substrate, a metal plating layer applied to a surface of the polymer substrate, and at least one selectively thickened region in the metal plating layer. The at least one selectively thickened region may assist in protecting the plated polymer component against wear and/or erosion.
