FLEXIBLE PIEZOELECTRIC SURFACE/WAVE MOTION PIEZOELECTRIC SURFACE/WAVE MOTION PROPELLING UNIT/WAVE MOTION PROPULSION MOVABLE BODY

摘要

PPROBLEM 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. PSOLUTION: 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.
