The design point of the designed forebody / inlet is flight mach number m = 6 and flight attitude h = 25km. the three - ramp, mixed external and internal compression hypersonic / inlet is chosen as representative geometry to be designed. nine types of hypersonic / inlet model with difference forebody length and total turning angle are obtained that the incidence angle of the first ramp and height of isolator are given
根據飛行任務要求,以飛行馬赫數6 ,飛行高度25km為設計點,給定前體預壓縮角、隔離段高度,對具有不同前體長度和不同總壓縮轉角的帶隔離段的前體進氣道進行了設計。 -
As the cam profile with constant - velocity - constant - acceleration ramp feature and with continuous higher derivative lift feature is widely adopted in the advanced high - speed internal combustion engines, the cam ramp profile is fitted with a reasonable function and the cam - lift profile is fitted with a polynomial function
考慮到高速內燃機的凸輪大多採用具有等加速-等速特徵的緩沖段和高階導數連續特徵的工作段型式,用等加速-等速函數擬合緩沖段實測升程數據,用整體式高次多項式函數擬合工作段實測升程數據。
