Aircraft Flight Trajectory Simulation Across Different Flight Phases

This paper describes a trajectory simulation program for different phases of aircraft flight, designed to provide comprehensive data sources supporting Strapdown and Integrated Navigation applications. The flight simulator implements phase-based trajectory modeling covering takeoff, cruise, descent, and landing maneuvers, generating diverse flight parameters including altitude, velocity, heading, atmospheric pressure, and aerodynamic characteristics. The program's architecture incorporates modular flight phase handlers with configurable transition logic between stages, utilizing kinematic equations and environmental models to simulate realistic flight dynamics. Additionally, the system features weather condition simulation modules that integrate atmospheric models to reproduce various flight scenarios under different meteorological conditions. The implementation employs parameterized trajectory generators with Kalman filtering techniques for smooth state transitions between flight phases. As a robust simulation tool, this program delivers comprehensive, accurate, and reliable data support for both flight simulation enthusiasts and aviation professionals, with extensible interfaces for custom navigation algorithm validation.
