Aircraft Cabin Safety and Interior Crashworthiness

2022-06-06
The certification of transport category cabin interiors requires a thorough understanding of Part 25 Transport Category aircraft cabin interior safety and crashworthiness regulations and compliance requirements. Regardless of whether it is a simple modification, a specialized completion (VIP or VVIP) or airline passenger configuration, engineers, designers, and airworthiness personnel must understand and adhere to these requirements. This two-day seminar will begin with a discussion of Commercial off the Shelf (COTS) test requirements.

Introduction to Cyber Security for Commercial Aviation

2022-04-07
Despite the advantages of electronic flight bags (EFB), passenger entertainment and email access during flights, and the ability to access aircraft repair manuals electronically, computer interconnectivity throughout aviation has opened the aviation sector to cyber-attacks that could impact flights, data, and safety. This two-day seminar is intended to introduce aviation professionals to the need to implement cyber security throughout commercial aviation including the supply chain.

Quantum Explanations for Destructive Interference in Engineering Decision Making

Engineering practice routinely involves decision making under uncertainty. Much of this decision making entails reconciling multiple pieces of information. As more information is collected, one is expected to make better and better decisions. However, conditional probability assessments made by human decision makers, as new information arrives does not always follow expected trends and instead exhibits interference effects. Understanding such positive or negative interference of two or more information inputs is necessary for a better modeling of the cognitive processes taking place in the customer or the end user's mind. Doing so enhances the likelihood that better products and product features can be designed. Quantum probability has been used in the literature to explain many commonly observed deviations from classical probability. Some examples include: question order effect, response replicability effect, Machina and Ellsberg paradoxes.

Optimal chassis suspension design for towbarless aircraft tractor taxiing system vibration isolation

2022-03-29
2022-01-0291
The towbarless aircraft tractor taxiing system (ATTS) is composed by the tractor vehicle and the aircraft, of which the nosewheel is lifted and transmit the power driven by the tractor to the aircraft, and the aircraft is towed to the destination in a long distance with a high speed of about 40 km/h. Compared to the traditional aircraft traction with the speed of 5 km/h and about 50 m distance, the ATTS can increase the airport operation efficiency and economy. However, the ATTS vibration becomes one significant problem, which will reduce the driver’s ride comfort and failure to the system structure, as the traction velocity increases and the tractor lacks of the chassis suspension. Due to the excellent vibration isolation characteristics, the air suspension is considered to install on the tractor, and the dynamic model of the ATTS with air suspensions is derived.

Researches on pedestrian protection have become a very important theme in automotive industry. Design for vehicle front-bumper system has proven rather essential and been extensively used to improve the vehicle performance of pedestrian protection. However, there are some limitations in the design of vehicle front-bumper system to meet a multiple-pedestrian impact conditions at the same time. In order to improve the vehicle performance of lower extremity and pelvis protection for pedestrian, a new type of front bumper airbag was developed. Firstly, based on Euro-NCAP evaluation rules, the Flex-PLI to vehicle and U-PLI to vehicle impact tests are carried out to evaluate the pedestrian protection performance of the initial structure. Secondly, the structural design of the bumper airbag is carried out, including the layout of the bumper airbag, the shape of the bumper airbag and the parameter design of the airbag. Finally, the performance of bumper airbag is tested and verified.
