All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The first aspect of the present application provides a method for optimizing short-distance landing of a transport aircraft airport, as shown in fig. 1, mainly including:
step S1, giving a grounding speed value range of the landing of the aircraft and an aircraft approach track angle value range.
In some alternative embodiments, the ground speed range is Vcg-1.15Vs, vcg is the ground minimum maneuver speed, and Vs is the aircraft stall speed; the value range of the aircraft approach track angle is-5 degrees to-8 degrees.
S2, dispersing a plurality of speed discrete points in the grounding speed value range, dispersing a plurality of track angle discrete points in the aircraft approach track angle value range, and combining the speed discrete points and the track angle discrete points into a plurality of input sequences.
In some alternative embodiments, at least three discrete points of speed are equally spaced apart within the ground speed range and at least three discrete points of track angle are equally spaced apart within the aircraft approach track angle range.
In this embodiment, vcg is typically 1.05Vs, calculated stall speed vs=48.07 m/s, and three ground speed discrete points are equally spaced apart, each ground speed V Id =[1.05Vs,1.1Vs,1.15Vs]. Three track angle discrete points are scattered at equal intervals, and each aircraft approach track angle theta ap =[-6°,-7°,-8°]。
The three ground speeds and the three aircraft approach path angles together can form 9 input sequences.
And S3, calculating the grounding attack angle of the landing grounding point and the grounding pitching attitude angle of the landing grounding point for each input sequence.
In some alternative embodiments, step S3 further comprises:
step S31, according to the maximum landing grounding sinking speed V ymax Ground speed V Id Calculating the grounding track angle theta Id :θ Id =V ymax /V Id
Step S32, according to the grounding track angle theta Id Ground speed V Id Aircraft approach track angle θ ap Calculating normal overload n of landing ground point y
n y =((θ ap ) 2 -(θ Id ) 2 ) (V Id ) 2 /294+1;
Step S33, according to normal overload n y Ground speedV Id Calculating the lift coefficient CL of the landing site Id :CL Id =19.6n y W/(Sρ(V Id ) 2 ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein W is the landing weight of the aircraft, S is the wing area, and ρ is the atmospheric density;
step S34, according to the lift coefficient CL of the landing grounding point Id Determining the ground attack angle alpha of the landing ground point Id
Step S35, according to the grounding attack angle alpha of the grounding point Id Ground track angle θ Id Determining a ground pitch attitude angle gamma for a landing ground point Id
In some alternative embodiments, in step S31, the maximum landing ground settlement speed is set to 1.5m/S. For different earthing speeds V Id Angle theta with approach path of aircraft ap The formed combined sequence can calculate the corresponding grounding attack angle alpha by the mode Id Ground pitch attitude angle gamma Id . In step S34, the ground attack angle α of the landing point is determined Id Other parameters, such as airport altitude, temperature, etc., are also required, and calculating the ground angle of attack of the landing ground point is a routine calculation process in the art, and will not be described in detail in this application. Finally in step S35, the ground attack angle α of the landing ground point Id And ground track angle theta Id The grounding pitching attitude angle gamma of the landing grounding point can be obtained by adding Id
And S4, determining a first difference value between the ground attack angle closest to the alarm attack angle and exceeding the alarm attack angle and the alarm attack angle, and simultaneously determining a second difference value between the ground pitching attitude angle closest to the ground wiping angle and exceeding the ground wiping angle and the ground wiping angle.
In the step, the floor wiping angle Atd is generally 13 degrees, the alarm attack angle Ayx is generally 12.7 degrees, and the floor wiping angle Atd can be specifically designed by oneself. For example, for ground speed V Id = 52.8814m/s, ground speed V Id Combined sequence of = -7 ° calculated ground angle of attack α Id 12.7785 ° ground pitch attitude angle γ Id 11.15316, the grounding attack angle of the group of sequences exceeds the alarm attack angle and is closest to the alarm attack angle, and the first difference value is12.7785 ° -12.7 ° =0.0785 °. For the ground speed V Id = 50.4777m/s, ground speed V Id Combined sequence of = -6 ° calculated ground angle of attack α Id 17.1379 ° ground pitch attitude angle γ Id For 15.43517 °, the ground pitch attitude angle of the set of sequences exceeds and is closest to the ground angle, the second difference being 15.43517 ° -13 ° = 2.43517 °.
And S5, when the first difference value is smaller than the second difference value, the grounding attack angle is a sensitive parameter, a critical attack angle is calculated, the critical attack angle is a set multiple of the alarm attack angle, otherwise, the grounding pitching attitude angle is a sensitive parameter, and a critical pitching attitude angle is calculated, and the critical pitching attitude angle is a set multiple of the ground wiping angle.
As can be seen from the above-mentioned embodiments, the first difference is smaller than the second difference, that is, the ground attack angle is a sensitive parameter, and when the ground attack angle is a sensitive parameter, the critical attack angle needs to be calculated. In some alternative embodiments, the multiple is set to 0.95. Accordingly, the critical angle of attack is 12.7x0.95=12.1°.
And S6, interpolating the grounding speed based on the critical attack angle or interpolating the aircraft approach track angle based on the critical pitching attitude angle to obtain the optimized grounding speed and the aircraft approach track angle.
According to the above embodiment, in the combined sequence with the same aircraft approach track angle, the ground speed is interpolated by the critical angle of attack of 12.1 ° to obtain the ground speed of 53.8m/s, at which time the aircraft approach track angle is unchanged and still is-7 °.
Similarly, if in step S5, the first difference is greater than the second difference, the ground pitch attitude angle is a sensitive parameter, a critical pitch attitude angle is calculated and obtained to be 13×0.95=12.35°, and then in the combined sequence with the same ground speed, the aircraft approach track angle is interpolated by the critical pitch attitude angle of 12.35 °, where the ground speed is unchanged and still 50.4777m/S.
