nseg
NSEG是美国兰利研究中心推出的飞行器起飞、爬升、巡航、加速、下降、减速和着陆等各个过程分析软件。(NSEG was developed to perform rapid aircraft mission analyses. It is based upon the
use of approximate equations of motion whose form varies with the type of flight
segment. Flight segments considered are takeoff, accelerations, climbs, cruises, descents,
decelerations, and landings. Layered atmosphere options are available. The program can
also be used for flight envelope mapping. NSEG provides the capability to analyze
aircraft missions from low to hypersonic speeds. Realistic and detailed vehicle
characteristics are input to NSEG to permit accurate mission analysis. NSEG allows
engine scaling so as to fit the design under analysis. NSEG contains several approximate
flight path optimization capabilities based on Rutowski energy-like criteria for
considering minimum time or fuel flight segments and maximum range segments during
climb or descent. Takeoff and landing analysis is based on the Air Force Flight
Dynamics Laboratory DATCOM method of high lift aerodynamic modelling)
