Abstract
The present invention discloses a pulse combustion turbine, particularly a disk-type pulse combustion turbine which has small volume. A pulse jet part of the present invention is changed into a coiling shape and is stacked with a blade wheel.
Description
The invention belongs to the gas turbine of Helmholtz's effect burner.
A kind of low pollution of domestic and international large batch of needs at present, economical and practical motors such as car and boat.The maturation of piston type machine is not thrown wearing for piston away, To Be Protected from Heat, cooling heat loss, burning are insufficient, unclean, uneconomical yet.The virtuous 222-223 page or leaf of free piston gas turbine " extraordinary motor " Liu's generation publishing house of Zhejiang University in 1991.Do not throw piston away yet.And have the isobaric gas turbine of impeller gas compressor, and needing the gas compressor of high speed rotating, structure, economy are all undesirable.
Be head it off, the textbook of delivering in recent years " gas impulse combustion technology " Zhou Weiguo, the certain herbaceous plants with big flowers 1-3 of Qin Dynasty page or leaf in May, 1997 publishing house of Tongji University both at home and abroad.A kind of pulse combustion turbine is disclosed, be to utilize the pulse jet part, both: pulse jet engine, or title pulse burner, be to utilize Helmholtz's effect, the inertia gas column of concussion, it is jet to burn, the rotor that promotes the impeller part rotates the motor of acting and the basic principle of pulse combustion turbine.The 9th page pulse burner is disclosed can be as the pulse jet part that promotes the wheel rotation acting.The 10-15 page or leaf discloses basic principle, the basic structure of pulse burner.The basic structure that the 9-10 page or leaf discloses pulse burner is: air and fuel one-way valve, mixing chamber, firing chamber, jet pipe.The 1-5 page or leaf discloses pulse burner still can realize the pulse jet function after bending to the multiform bend pipe." mechanical engineering manual " mechanical engineering manual motor engineering handbook editorial board, General Board: Shen Hong the 2nd plume mechanics 5-431984 China Machine Press, the bend pipe inner fluid is disclosed, when coiling radius when being 6-7 times of caliber, resistance significantly diminishes, and fluid property is better than other shape bend pipe.Textbook " physics " Beijing Teaching Materials Writing Group of Bureau of Education compiles, Middle Schools in Beijing textbook People's Press's the 2nd the 54th page in January, 1977.Disclose the position relation (figure is arranged) of a kind of gas turbine impeller part and nozzle segment, and can make the wheel rotation acting." dong feng 4 internal combustion locomotive " Dalian Locomotive Vehicle Factory, Ministry of Railways is compiled the 220th page of (Fig. 8-22) nineteen ninety-five publishing house of Dalian University of Technology.Disclose a kind of turbine, can have been promoted the rotation acting by the transient pressure air-flow.The virtuous 238-242 page or leaf of " extraordinary motor " Liu's generation publishing house of Zhejiang University in 1991, the pulse jet function that how to realize the pulse jet part is disclosed.In sum, though the desirable solution of prior art the cleaning of pulse combustion turbine, the thermal efficiency, life-span, economic dispatch problem, realized the running acting.But in the pulse combustion turbine because of prior art, the shape of its pulse jet part is long straight, and misfits with impeller shape partly, and cooperation position is not compact, causes body huge, and is loose.Can not satisfy the harsh requirement to its motor volume such as modern car and boat, so be not widely adopted.The inventor of large quantities of affiliated technical fields and technician have been subjected to the destructive strike of the British army-" aviation knowledge " for German army makes pulse jet engine when " World War II ".After " World War II ", when large quantities of affiliated technical field technician are U.S. air force development pulse jet engine when " cold war ",, be forced to change one's profession to develop isobaric gas jet engine because the aviation machine to the harsh requirement of volume weight, is competed failure.
Task of the present invention provides a kind of pulse combustion turbine of small body type, thereby can conveniently put in the car and boat etc., is extensive use of as motor.
For solving above-mentioned task, must partly use long straight pulse jet in the prior art pulse combustion turbine instead coiling shape structure, and partly form superimposed position relation with the impeller plate.
Feature of the present invention shows that its design is ingenious, makes simply, and the effect that reduces the bodily form is remarkable.Pulse jet partly is the coiling shape; Impeller partly is a plate-like, and they can be fully superimposed, and axial-radial all coincide, and is not outstanding, also do not separate.In the pipe of pulse jet part the gas flow resistance hour, when both the power of pulse combustion turbine was big, its bodily form was significantly little.Because the axial view of its pulse jet part and impeller is circular; Overall seemingly sphere meets mathematical theory: equal area circular perimeter length of side minimum, equal volume spherical surface minimum.
Claims (1)
- A kind of pulse combustion turbine that adopts pulse burner, the inertia gas column of this pulse burner utilization vibration carries out pulse-combustion, comprises Helmholtz's type; This pulse combustion turbine is characterised in that: the pulse jet of pulse burner partly is coiling shape structure, and superimposed with the impeller plate.
