Abstract

The results of a Pluto landing analysis study for a fast, hyperbolic approach trajectory are presented by assuming the use of a novel entry, descent, and landing system called an enveloping aerodynamic decelerator. A landing site uncertainty analysis is performed for an 11 September 2040 arrival by means of a Monte Carlo simulation to map key trajectory, aerodynamic, system, and atmosphere uncertainties to landing zone errors. The estimated 3 [Formula: see text] landing error ellipse is about 430 by 190 km. The band of feasible landing sites is between 35°N and 10°S latitude on the surface of Pluto.

从快速双曲线轨道登陆冥王星的任务分析

通过假设使用一种称为包络式气动减速器的新型进入、下降和着陆系统，提出了冥王星快速双曲进近轨迹的着陆分析研究结果。通过蒙特卡罗模拟，对2040年9月11日着陆的着陆点不确定性进行了分析，将关键的轨迹、空气动力学、系统和大气不确定性映射到着陆区误差。估计的3[公式:见文本]着陆误差椭圆约为430乘190公里。可行的着陆点范围在冥王星表面北纬35°到南纬10°之间。

期刊介绍： This Journal, that started it all back in 1963, is devoted to the advancement of the science and technology of astronautics and aeronautics through the dissemination of original archival research papers disclosing new theoretical developments and/or experimental result. The topics include aeroacoustics, aerodynamics, combustion, fundamentals of propulsion, fluid mechanics and reacting flows, fundamental aspects of the aerospace environment, hydrodynamics, lasers and associated phenomena, plasmas, research instrumentation and facilities, structural mechanics and materials, optimization, and thermomechanics and thermochemistry. Papers also are sought which review in an intensive manner the results of recent research developments on any of the topics listed above.
