Embodiment

[0043] Such as figure 1 , 2 As shown, an algorithm for the flap adjustment amount of a multi-engine turboprop aircraft yaws and sideslips, including the sideslip angle of the aircraft 1, the flap adjustment amount 2, the aileron (flap adjustment reference) 3, and the flap 4 .

[0044] An algorithm for the amount of aileron adjustment when a multi-engine turboprop aircraft yaws and sideslips, including steering wheel deflection angle θ and deflection direction 1, flap adjustment amount L value 2, aileron (flap adjustment reference datum) 3, flap 4. Determination of flap adjustment direction.

[0045] The first step is to ensure that the aircraft is in level flight by deflecting the steering wheel to the left by an angle θ of 6° according to sideslip and yaw.

[0046] The second step according to the formula The value L of the flap adjustment amount is calculated to be 2mm.

[0047] The third step is to determine the value of shortening L of the left flap to be 2 mm or the...

Abstract

The invention belongs to the technical field of aviation, and provides a method for calculating the flap adjusting amount during yaw and sideslip of multi-turboprop aircraft in order to solve the problems of yaw and sideslip of the multi-turboprop aircraft. The method comprises the steps that 1, a deflection angle theta and the deflection direction of a steering wheel are obtained; 2, according to a formula, a flap adjusting amount numerical value L is calculated, and K is a flap adjusting coefficient; and 3, the flap adjusting amount L and the adjusting direction are obtained according to the deflection direction of the steering wheel.

Description

technical field [0001] The invention belongs to the technical field of aviation, and relates to a method for calculating the adjustment amount of double-slit retreating flaps when yaw and sideslip occur in a multi-engine turboprop aircraft before leaving the factory. Background technique [0002] The process of aircraft assembly is that parts are assembled into components, components are riveted into components, and components are docked into aircraft. During the aircraft manufacturing and assembly process, error accumulation problems such as part manufacturing tolerances, component assembly deviations, and component riveting assembly errors cannot be avoided, especially for multi-engine aircraft. The accumulation of differences in factors and differences in fuel consumption may exacerbate a series of problems such as yaw and sideslip of the aircraft. [0003] The above problems are difficult to find and solve in the ground debugging stage. At present, there is no algorithm ...
