Abstract

(57) [Summary] (Modified) [PROBLEMS] The present invention relates to a tire structure for an aircraft for reducing frictional resistance between a tire of the aircraft and a landing contact surface when the aircraft lands. SOLUTION: By mounting a plurality of semicircular wing-shaped projections 5 receiving air resistance on a landing tire 4 of an aircraft, the aircraft can use landing gear to prepare for landing. When the vehicle comes out of the aircraft, the landing tire of the aircraft can be rotated in advance in the direction of landing, thereby reducing the frictional resistance between the landing tire of the aircraft and the landing contact surface. Thus, the impact load on the fuselage, axle, tires, etc. of the aircraft is reduced, so that the aircraft can operate and land more safely.

Description

[Detailed description of the invention]   [0001] [Technical field to which the invention belongs]   This invention is based on a semi-circular vane-shaped A tire that has multiple protrusions and automatically rotates in the direction of landing of the aircraft Wearing reduces the frictional resistance between the tire and the tread when the aircraft lands Things.   [0002] [Prior art]   Conventionally, when the aircraft is in landing touchdown, rubber tires for aircraft landing Because it does not rotate, it produces white smoke instantaneously due to remarkable frictional resistance with the ground surface Cars that generate heat and cause puncture accidents due to impact when touching down, and support tires and aircraft There was a great adverse effect on shaft and other deterioration damage.   [0003] [Problems to be solved by the invention]   In order to eliminate the conventional drawbacks, the present invention proposes that the aircraft By rotating the tire in advance in the landing direction, And reduce frictional resistance between the ground and the ground, contributing to safer aircraft landing. is there.   [0004] [Means for Solving the Problems] Now, let's explain the means while following the drawing, (A) On both sides or one side of the aircraft tire, Multiple semicircular blade-shaped projections that receive air resistance of the number and size that matches the size The tire to be manufactured is manufactured by molding at the time of manufacturing the aircraft tire (FIGS. 1, 2, 3, (Fig. 4) and wear the aircraft. (B) On both sides or one side of the aircraft tire, Has the same outer circumference as the tire and receives air resistance of the number and size that matches the tire size A baking type product having a plurality of semicircular blade-shaped projections (FIG. 5) is bonded. Alternatively, a crimped tire (FIG. 6) is manufactured and mounted on the aircraft. (C) A semi-circular wing-shaped projection that receives air resistance when worn on the aircraft As described in [Claim 3] above, the direction of The left and right tires move toward the landing direction of the aircraft due to air resistance. The direction of the rotating projection. (D) Regarding the orientation of the projections when manufacturing for the aircraft, see (c) above. The center of the axle of the aircraft so that it rotates in the landing direction of the aircraft From both sides (Fig. 7) (Fig. 8) and one side (Fig. 9) (Fig. 10) I do.   [0005] [Embodiment of the invention]   The orientation of the semicircular wing-shaped projections when mounting on the aircraft tire wheel Depending on the aircraft, depending on the size of the wheels, the shape of the axles and tire wheels, There are cases where there are right and left for each from the center of the aircraft axle. Each tire rotates in the direction of landing of the aircraft due to air resistance. Make the direction of the rolling projections.   In the present invention, these structures are manufactured and mounted on the aircraft.   [0006] [Effect of the invention]   Therefore, when the aircraft lands, the landing tire wheels of the aircraft The aircraft automatically rotates before landing, so when the aircraft lands, the ground contact There is little resistance, and in addition to tire puncture cases, the impact of the aircraft and axle at the time of touchdown is reduced and the aircraft It is effective in preventing damage deterioration.
