Abstract:
PROBLEM TO BE SOLVED: To attain improvement of dynamic lift of a wind power generator and an aircraft by developing a wing shape capable of generating the dynamic lift over low to high wind speed areas since in a conventional fixed wing, the dynamic lift is large at the high wind speed area but the dynamic force at the low/middle wind speed area is small and the dynamic lift by magnus effect is large at the low/middle wind speed area but a magnus cylinder becomes air resistance at the high wind speed area. SOLUTION: The composite magnus type wing generates the dynamic lift of the fixed wing and the magnus force by mounting the rotation magnus cylinder to a middle of the fixed wing. The composite wing can generate the dynamic lift in a wide range from the low wind speed area to the high wind speed area by the dynamic lift by the magnus force at the low wind speed area and the dynamic lift by the fixed wing at the high wind speed area. Power generation at the wider wind speed area than conventional becomes possible by adopting it to a rotation wing of the wind power generator and performing control of the rotation number of the magnus wing. If it is adopted for the wing of the aircraft, it becomes a short fixed wing and taking off/landing in a short distance becomes possible. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To reduce noise and eliminate an exhaust gas and to realize energy-saving as a conventional light aircraft or a helicopter or further as an aircraft for air transportation not competing in speed, monitoring and service from the air above in an agriculture and forestry fishing industry and sight-seeing by attaching a wave motion propelling unit to it. SOLUTION: The conventional engine, motor, transmission mechanism or the like are not required. (1) A wing surface itself is made to a bendable [wave motion piezoelectric membrane/wave motion piezoelectric surface] by application of a piezoelectric body. (2) The same membrane surface is made complementary to increase thrust and is attached to a gliding object to realize self-actuated flight. (3) It is made to a multiple wave motion piezoelectric surface to create a blown wing upper surface laminar flow and vertical taking off/landing is realized. Other required articles are a solar battery, a secondary battery and an electronic circuit for piezoelectric surface driving. It is light weight, flight at high height is realized and manufacturing of a large size aircraft can be realized. Mass transportation becomes possible utilizing the prevailing westerlies.

PROBLEM TO BE SOLVED: To solve the problem wherein a means using lifting power by a pressure difference to be generated by a difference between an upper and a lower angles formed in a blade of a wing by propelling force is used to float an article such as a robot in the air and large propelling force is necessary. SOLUTION: A hydraulic device is used to directly generate buoyancy, and at the same time, wind force is taken to push the article upward, and the article is raised with slide of a cylinder.

Abstract:
PROBLEM TO BE SOLVED: To provide an airplane using hydrogen as fuel by a fuel reforming method. SOLUTION: In the airplane, a gas turbine is mainly driven by jet fuel (light oil) to cause intense air pollution. Depletion of oil resources approaches after a lapse of ten and several years. Accordingly, development and manufacture of the experimental airplane are started by two (German and Russian) companies in cooperation. In the experimental airplane, liquefied hydrogen is stored in each a refrigerated tank 15 of a temperature of -253°C and a withstanding pressure of 1.5 atm. The liquefied hydrogen fuel has a volume 4.2 times the jet fuel. The tank 15 of the withstanding pressure of 1.5 atm cannot be stored in main wings and a center wing. Accordingly, an upper part 14 of a body 9 is expanded, and the cylindrical fuel tanks 15 for liquefied hydrogen and a heat insulation material 16 therefor are stored in the upper part 14. Because a transport/refrigeration apparatus is newly provided, liquefied hydrogen causes a high cost. The experimental airplane is provided with fuel reformers 2 developed for the purpose of supply of hydrogen to a fuel cell of a fuel cell automobile, separates hydrogen of liquefied fuel (mainly light oil, artificial petroleum in the future), and uses the hydrogen as the fuel to drive propfan engines 7, 19.
