Embodiment 1
[0075] Known parameters: as attached figure 1 , there are 3 (n=3) constant speed phases P1, P2, and P3, P1 section speed V 1 =300m / s, the flight distance is S 10 =30000m, the flight time is T 10 =100s; P2 section speed is V 2 =200m / s, the flight distance is S 20 =16000m, the flight time is T 20 =80s; P3 stage speed is V 3 =100m / s, the flight distance is S n0 =6000m, the flight time is T 30 =60s; obviously the total flight distance S of the original plan 0 =52000m and time T 0 =240s; as attached figure 2 , the expected total flight distance S f =80000m and time T j = 540s.
[0076] Unknown parameter: as attached figure 2 , find S if (i=1, 2, 3), T if (i=1, 2, 3).
[0077] The program implementation process is as follows:
[0078] Step 1: According to the original planned total flight distance S 0 and time T 0 and the expected total flight distance S f and time T f , calculate the flight distance difference ΔS and the time difference ΔT.

Embodiment 2
[0084] Known parameters: as in Example 1, keeping other parameters unchanged, the expected total flight distance S f =60000m and time T f = 640s.
[0085] Unknown parameter: S if (i=1, 2, 3), T if (i=1, 2, 3).
[0086] The program implementation process is as follows:
[0087] Step 1: According to the original planned total flight distance S 0 and time T 0 and the expected total flight distance S f and time T f , calculate the flight distance difference ΔS and the time difference ΔT.
[0088] ΔS = S f - S 0 = 8000 m ΔT = T f - T 0 = ...
Embodiment 3
[0095] Known parameters: as in Example 1, keeping other parameters unchanged, the expected total flight distance S f =60000m and time T f = 540s.
[0096] Unknown parameter: S if (i=1, 2, 3), T if (i=1, 2, 3).
[0097] The program implementation process is as follows:
[0098] Step 1: According to the original planned total flight distance S 0 and time T 0 and the expected total flight distance S f and time T f , calculate the flight distance difference ΔS and the time difference ΔT.
[0099] ΔS = S f - S 0 = 8000 m ΔT = T f - T 0 = ...
