  • AUTOMATIC CONTROL SYSTEM OF AIRCRAFT, EFFECTIVENESS EVALUATION METHOD THEREFOR, AND MEASUREMENT APPARATUS FOR THE AUTOMATIC CONTROL SYSTEM
    Publication number: 20250368320
    Abstract: An automatic control system of an aircraft according to an embodiment of the present invention includes: a measurement unit that measures, as preview information, a difference between a wind speed actually received by an aircraft and a wind speed to be encountered in future, adds information for identifying an estimation error or validity/invalidity of a measured value to measurement information, and outputs the resultant information; a control surface that controls lift, drag, or an attitude of the aircraft, or an apparatus that controls thrust; and a control arithmetic unit that calculates an angle of the control surface or the thrust to reduce an action of the wind speed exerted on an aircraft, on the basis of a wind speed value in a planned flight direction of the aircraft, the wind speed value being measured by the measurement unit.

  • Low pollution fuel
    Patent number: 6599336
    Abstract: To provide a low pollution fuel capable of obviating imperfect combustion of fuel in a diesel engine, etc., and fundamentally solving the exhaust gas problems without depending on the conventional symptomatic method. The low pollution fuel is composed of kerosene, light oil or heavy oil which is blended with an oxygen-contained hydrocarbon composed of an olefin-based hydrocarbon as a starting material, such as ether, alcohol or glycol.

  • Low pollution fuel
    Publication number: 20020023384
    Abstract: To provide a low pollution fuel which is capable of fundamentally solving the problem of exhaust gas discharged from trucks, etc. which use light oil, etc. as their fuel, without depending on the conventional symptomatic measures. The low pollution fuel is obtained by blending an ethylene glycol based compound having a CH2CH2 group in a molecule formula with a liquid hydrocarbon.
