基于改平策略的全航段起飞越障一体化计算研究OA
Research on integrated calculation of full-flight takeoff obstacle clearance based on level-off strategies
现有飞机性能软件在分析起飞越障时,虽能获得障碍物限重,但当需要越过第四航段障碍物时,需要人工决策才能合理评估障碍物限重.通过深入分析CCAR25部规章条款的意图,提出一种精准的总、净起飞飞行航迹仿真算法,建立涵盖关键约束项的全航段起飞越障计算模型.通过不同改平策略的整合,实现起飞越障的一体化计算.结果表明:相比传统越障模型,本文所提模型在越障评估中障碍物限重提升可达24%,为国产民用飞机的高效安全运行提供了更为可靠的保障.
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.
