Pressure Suit Design Considerations for Crew Extraction & Recovery

41st International Conference on Environmental Systems, 2011
This paper provides insight into pressure suit design features associated with crew rescue protocol during pre-launch, post-landing, and mission abort contingency scenarios. A review of historical rescue aids, the scenarios in which they were designed to be used, and common techniques employed by rescue personnel will be presented, in addition to crew ...

Concepts for an International Space Station Crew Transfer/Recovery Vehicle

36th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2000
The International Space Station is currently being built in space. Over the next 10-20 years, it will be desirable to have a multi-purpose vehicle that can transport crew and supplies independent of the space shuttle. The objective of this study is to establish the requirements for such a vehicle and evaluate preliminary concepts to fulfill this ...

Solving airlines disruption by considering aircraft and crew recovery simultaneously

Journal of Shanghai Jiaotong University (Science), 2013
When disruptions occur, the airlines have to recover from the disrupted schedule. The recovery usually consists of aircraft recovery, crew recovery and passengers’ recovery. This paper focuses on the integrated recovery, which means above-mentioned two or more recoveries are considered as a whole. Taking the minimization of the total cost of assignment,

Crew Recovery and Contingency Planning for a Manned Stratospheric Balloon Flight – the StratEx Program

Prehospital and Disaster Medicine, 2016
AbstractThe StratEx program used a self-contained space suit and balloon system to loft pilot Alan Eustace to a record-breaking altitude and skydive from 135,897 feet (41,422 m). After releasing from the balloon and a stabilized freefall, the pilot safely landed using a parachute system based on a modified tandem parachute rig.

A mathematical model for integrated aircraft and crew recovery after a disruption: a Benders’ decomposition approach

Journal of Modelling in Management, 2022
Purpose Airline scheduling is an extremely complex process. Moreover, disruption in a single flight may damage the entire schedule tremendously. Using an efficient recovery scheduling strategy is vital for a commercial airline. The purpose of this paper is to present an integrated aircraft and crew recovery plans to reduce delay and prevent delay ...

Point-of-Care Ultrasound Utility and Potential for High Altitude Crew Recovery Missions

Aerospace Medicine and Human Performance, 2017
INTRODUCTION: Flights to high altitude can lead to exposure and unique pathology not seen in normal commercial aviation.METHODS: This paper assesses the potential for point-of-care ultrasound to aid in management and disposition of injured crewmembers from a high altitude incident. This was accomplished through a systematic literature review regarding

Tree Crew Perspectives on Wood Product Recovery from Utility Vegetation Management

Arboriculture & Urban Forestry, 2020
Utility vegetation management generates large quantities of wood that require disposal. To explore opportunities for reducing wood waste and promoting wood recovery, we evaluated the perceptions and experiences of utility-contracted tree crews regarding a wood recovery program.

Large-Scale Airline Crew Recovery Using Mixed-Integer Optimization and Supervised Machine Learning

Transportation Science
Airlines take a variety of actions to recover schedules of their aircraft, crew, and passengers from operational disruptions. Aircraft are typically recovered first, followed by crew recovery, and then passenger recovery. This paper aims to repair disrupted crew schedules while ensuring the feasibility of previously decided aircraft recovery plans and ...

Optimal airline crew recovery considering flight time constraint and paring rule

Proceedings 2011 International Conference on Transportation, Mechanical, and Electrical Engineering (TMEE), 2011
This article has proposed a crew recovery methods based on previous researches. After taking into account of the current assignment and other rules, we created a mathematical model to solve this problem. As we can determine the scope of the crew recovery, lingo solver is more convenient.
