基于改平策略的全航段起飞越障一体化计算研究
Research on integrated calculation of full-flight takeoff obstacle clearance based on level-off strategies
摘要
Abstract
Existing aircraft performance software can determine obstacle weight limits when analyzing takeoff clear-ance.However,when it comes to clearing obstacles during the fourth segment,manual decision-making is required for a reasonable evaluation of the obstacle weight limit.Grounded in a comprehensive analysis of the intentions be-hind CCAR25 regulatory clauses,this paper proposes a precise simulation algorithm for gross and net takeoff flight paths and establishes a comprehensive model covering key constraints for full-segment obstacle clearance assess-ment.This model achieves an integrated calculation of obstacle clearance analysis through different level-off height strategies.Compared to traditional obstacle-clearance models,the simulation results demonstrate a possible en-hancement of obstacle-limited takeoff weights by up to 24%in this model's assessments.This research provides more reliable support for the efficient and safe operation of domestic civil aircraft.关键词
