摘要:
The flexible crankshaft for software controllable aircraft wheel drive represents a steel flexible cable, located in a flexible plastic-rubber guide which is adapted for the transfer of the torque along all axis, and is connected on one end to a power distributor, (or directly to a power generator unit if the construction is with one wheel) and with the other end, i.e. a small drive adapter, rests on the tyre of the aircraft wheel. The power distributor receives entry power from the power generator motor (electrical motor with gearshift switches, couplings, etc. or from air pressure in "pneumatic" construction). The flexible crankshaft rotates moved by the power distributor or the motor (across the redactor, multiplicators, gearshift, valves, couplings, etc.) and transfers the torque through the adapter, to the tyre wheel itself, and in this way rotation of the wheel occurs. The rotation speed is regulated with the aid of a program CPU or own microcontroller, and always turns the wheel at the exact program calculated optimal rotation speed, adjusted for landing. Furthermore the flexible crankshaft can be constructed as a flexible, i.e. flexible high-pressure pneumatic pipe, where in this case through them pressurised air is brought to small contact adapters (then whose construction, as with pneumatic tools, e.g. pneumatic drills, pneumatic screwdrivers, etc.) so they are powered in this way, i.e. carryout wheel rotation. In this way we have prevented wear of tyres when landing, and we have enabled safe landing of aircraft, without fear that crashes will occur in relation to wheels - tyres (blow out, dynamic burdening of the wheel, etc.). Furthermore, software control prevents the rotation of wheels during retraction (or lowering) and in this way prevents the occurrence of the damaging effects of so called gyroscopic moment and additional dynamic burdening of landing gear. This invention has an innovative approach as it allows installation in all existing aircraft, as the flexible crankshaft (with small adapter) does not exceed the existing external dimensions of wheels, rather enables that the power generator unit (which as a rule is of a larger dimensions and takes up a fair amount of space) is located anywhere in the fuselage or wing of the aircraft. In this way it does not occupy additional space in the already narrow space for wheel storage, as the transfer of the torque from it to the wheel is achieved across the mentioned flexible crankshaft which is flexible along all axis, so that it can be pulled from any location in the fuselage or wing of the aircraft to the wheel. Also it is possible to very easily install the invention in the very production of the aircraft. By applying this solution, i.e. this type of invention, unbelievable multiple savings are provided to airline companies; due to saving wear of tyres (their length of use is extended 4-5 times), due to current loss of flight time of aircraft due to changes of tyres, and also due to the contribution to safety of air traffic because it prevents crashes due to tyre blowouts when landing (concord example) and many others.
