Abstract:
The present invention aims to provide a modular jet trainer aircraft (1) which can be reconfigured to provide a plurality of different handling aircraft which will be particularly beneficial in the training of pilots. For example, the present invention provides a base structure on which elements can be changed in order to alter the handling capabilities, manoeuvrability and power of the aircraft. The aircraft may have a first basic configuration (1) which enables a pilot to learn relatively basic handling skills. The propulsions system and/or wing structures can then be changed to provide an aircraft (11) with more sophisticated handling and greater power capabilities. The invention involves the engine (17) being located fully outside the fuselage structure (14) whilst still being positioned on the centre-line of the fuselage (14) and with the engine's line of thrust directed through the centre of the fuselage and close to the aircraft's centre of gravity. By achieving this, the expensive design of the fuselage as primary or airworthy-critical structure can be completed independently from the installation of the engine.

본 발명은 조인드윙형 무인항공기에 관한 것이다. 더욱 상세하게는, 동체; 상기 동체의 양측에 형성되며, 양 끝단이 상기 동체의 선미 방향을 향하는 삼각형 형태로 이루어지는 메인윙; 양 끝단은 상기 메인윙과 연결대로 연결되며 상기 메인윙의 상부에 배치되어 상기 메인윙과 함께 조인드윙 형태를 이루는 상부윙; 상기 상부윙에 구비되며 추진력을 발생시키는 프로펠러; 상기 메인윙의 상면 중앙부 및 상기 상부윙의 하면 중앙부와 결합되는 수직날개; 및 상기 수직날개의 후미에 회동 가능하게 구비되어 방향을 조절하는 방향타를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 메인윙 및 상부윙의 형상에 의해 양력이 향상되어 좁은 공간에서도 용이하게 착륙할 수 있고, 비행 효율 및 이착륙 성능을 향상시킬 수 있는 효과가 있다.
Abstract:
Described herein are laminate structures with enhanced sound-damping properties and mechanical properties. The laminates are composed of an interlayer structure disposed between a first glass substrate and a second glass substrate, wherein the interlayer is composed of a polymer layer designed such that sound attenuation or damping by the laminate is optimized. The laminates described herein may be used in vehicles or architectural panels. In one or more embodiments, the laminate may be disposed in an opening of a vehicle body. Where the vehicle body is an automobile, the laminate could be used as a windshield, a side window, sunroof or rear windshield. The body of some embodiments may include railcar, aircraft or seacraft. In other embodiments, the laminate may be used in architectural panels, which may include a window, an interior wall panel, a modular furniture panel, a backsplash, a cabinet panel, or an appliance panel.
Abstract:
Lo aeronave conforma un volumen sustentador que incluye al menos parte del cuerpo central en que se aloja la carga a transportar, preservando dicho volumen, un perfil alar convencional en sentido longitudinal de la aeronave, que en sentido transversal se proyecta simétricamente hacia ambos lados, a partir del eje longitudinal en sendos primeros tramos con diedro negativo y flecha negativa, hasta sendos puntos de inflexión a partir de los cuales se proyectan sendos segundos tramos, distales, con diedro positivo y flecha positiva hasta los extremos de la envergadura alar.
Abstract:
A composite structural component is disclosed. The composite structural component can include a lattice structure, a casing disposed about at least a portion of the lattice structure, and a skin adhered to a surface of the casing. The lattice structure and the casing can be formed of a polymeric material and the skin can be formed of a metallic material.
Abstract:
A thin, cured gel gasket is disclosed, including methods of making the thin gel gasket and the use of the thin gel gasket in an aircraft joint. In one embodiment, the thin gel gasket has no skeleton or other structure and is comprised of only a cured polyurethane gel and has a thickness of less than about 12 mill. It is manufactured using a release film that is adapted in a number of ways to make release from the gel prior to use easier. In one method of making and using the thin gel gasket, it is applied to a joint which is subject to compression, in one embodiment, a lap joint of an aircraft fuselage.
Abstract:
A wing flap control system on a wing comprising at least two control plates having an opening sized to accommodate a drive shaft, a drive shaft that engages each of the openings in each of the plurality of plates, a sprocket rotatively affixed the drive shaft with the drive shaft penetrating the other control plate, at least two idler sprockets between the control plates, a chain wrapped around the sprocket and idler sprockets, a support arm rotatively coupled to the chain by a chain shoe and to a foreflap, a link arm rotatively coupled to the support arm and to a flap, where movement of the drive shaft causes the foreflap and flap to extend and retract to increase or decrease the surface area of the wing.
