Evidence of comprehensive hazard identification is a crucial component of any aerospace certification argument. Historically, in the early stages of the aerospace safety assessment process, hazard identification has been performed through use of hazard checklists – derived from lists of previously identified or experienced hazards. The arguments used in support of this approach are predominantl...

Aerospace medicine is the medical discipline responsible for assessing and conserving the health, safety, and performance of individuals involved in air and space travel. With the upward trend in airline travel, flight-related oral conditions requiring treatment have become a source of concern for aircrew members. Awareness and treatment of any potential physiological problems for these aircrew...

Superplastic sheet thermoforming has been identified as a standard processing route for the production of complex shapes, especially in the aerospace industry. Ti-Al-Mn (OT4-1) alloy is currently being used for aero engine components as well as other aerospace applications by forming through a conventional route which is typically cost, labour and equipment intensive. The Ti-Al-Mn alloy (made a...

One of NASA's four main product lines is developing and transferring to U. S. industry enabling technologies required for next generation aerospace vehicles as part of the Aerospace Technology Enterprise. This paper overviews the Ultra Efficient Engine Technology (UEET) Program, NASA's focused aerospace propulsion technology program. The UEET Program emphasizes technology development in six sel...

Aerospace vehicle design includes several disciplines with often-conflicting requirements. A formal system design framework is developed in this research where the designer coordinates with disciplinary experts to find an overall optimized design while simultaneously optimizing disciplinary objectives. The overall system objective function chosen in the preliminary design is minimum production ...

Aerospace industry has been involved in virtual simulation for design and testing since the birth of virtual reality. Today this industry is showing a growing interest in the development of haptic-based maintenance training applications, which represent the most advanced way to simulate maintenance and repair tasks within a virtual environment by means of a visual-haptic approach. The goal is t...
