Title: Dual-purpose aircraft having rotary wing and fixed wing
Inventor: YANG SHIAN-DUNG
IPC: B64C29/00
Filed: 1999-04-19
Granted: 2000-08-21
Abstract: This invention provides a kind of dual-purpose aircraft comprising the rotary wing and the fixed wing. It is a new dual-purpose aircraft that provides vertical takeoff/landing function in the rotary wing mechanism and the high-speed cruising function of the fixed wing aircraft. The body shape is similar to conventional helicopter that configures with double-decked disks on top of the body. Each disk extends two blades on the perimeter to form the main rotary wings. The two disks with the blades are rotating in the reversed direction driven by the main engine so that the torque acted on the body by the rotation of two disks are balanced each other. Further, the body tail will be mounted with a tail rotary wing which is driven by another engine (sub-engine) to provide the forward thrust of aircraft flying in fixed wing mode. The tail rotary wing can adjust the direction of the thrust which is similar to the ""vector thrust"" function in advanced aircraft. During the taking off of the dual-purpose aircraft, the disks are rotating; the blades on the perimeter of disks are used to generate the lifting force to take off with the rotary aircraft mode. After reaching the cruising speed and height, the disks will stop rotating; the lifting force is generated by advancing of the wing section of disks such that the aircraft can fly with the fixed wing aircraft mode. When the aircraft arrives at the destination, the flying speed slows down and the disks restart rotating; then, use the rotary aircraft mode to land the aircraft.

Granted: 2001-04-21
Abstract: A backup energy unit for an electrical device having a power source, an operational load, and containing a layered electrical device having a top exterior surface and a bottom exterior surface, such as an integrated chip or layered circuit board. The energy unit is made up of at least one energy storage device. This energy storage device is made up of a dielectric material and a first and a second electrical storage conducting layer. The dielectric material lies between the first and second electrical storage conducting layers. Further, the dielectric material exists between the top exterior surface and bottom exterior surface of the layered electrical device. The energy unit is further made up of a voltage detector to detect a potential level of the power source. When the voltage detector detects a power source disruption, that is when the potential level of the power source is below a first voltage state, it controls a switcher. This switcher disconnects the power source from the operational load and connects the energy storage device to the operational load when the voltage detector detects a power source disruption. Thus, when the power source is disrupted, the energy storage device provides electrical power to the operational load.
