Incident-response monitoring technologies for aircraft-cabin air quality
Poor air quality in commercial aircraft cabins can be caused by volatile organophosphorus (OP) compounds emitted from the jet engine bleed air system during smoke/fume incidents. Tri-cresyl phosphate (TCP), a common anti-wear additive in turbine engine oils, is an important component in today’s …

Jet oscillation applied for aircraft cabin ventilation using active flow control actuators
Maintaining a healthy cabin environment during flight relies on continual extraction of fresh air from the engine. To meet passengers' expectation for more comfortable cabin which requires improved air supply and address the ever critical energy and emissions concerns, novel air delivery methods …

Quantifying Air Distribution, Ventilation Effectiveness and Airborne Pollutant Transport in an Aircraft Cabin Mockup
… during flight inspired this research into cabin air quality, which is closely related to its airflow distribution, ventilation effectiveness and airborne pollutant transport. The experimental facility is a full-scale aircraft cabin mockup. A volumetric particle tracking velocimetry (VPTV) …

System Identification and Optimization Methodologies for Active Structural Acoustic Control of Aircraft Cabin Noise
… has shown much promise for reducing interior cabin noise in aircraft by applying control forces directly to the fuselage structure. Optimal positioning of force actuators for ASAC presents a challenging problem however, because a detailed knowledge of the structural-acoustic coupling in the …

Analysis of Path Loss from a Transmitter in an Aircraft Cabin to an Exterior Fuselage-Mounted Antenna
… to investigate the threat posed to commercial aircraft by on board electronic transmitters in the passenger cabin and the cargo holds of large transport aircraft. These transmitters may be in the form of unintentional use of portable electronic devices or even intentional radio frequency (RF) …

MODELING AND DESIGN OF A SMART DOUBLE-PANEL SYSTEM FOR THE CONTROL OF SOUND TRANSMISSION INTO AIRCRAFT CABIN
Nowadays, the level of interior cabin noise in modern aircraft has been reduced significantly compared with noise levels in the past because the double-panel design of aircraft sidewall systems has been much optimized. Furthermore, new composite materials are now used in the design of trim panels …

Development of hybrid particle tracking algorithms and their applications in airflow measurement within an aircraft cabin mock-up
… full-scale, five-row section of a Boeing 767-300 aircraft cabin mockup. A complete experimental procedure was developed and strictly followed throughout the experiment. Both global flow field at the whole cabin scale and the local flow field at the breathing zone of one passenger were studied. …

Dynamic Simulation of General Aviation Cabin Environments and Occupant Restraint Systems
… Safety Board (NTSB) has concluded that aircraft cabin environments place the occupant at high risk of suffering severe injuries in an emergency crash situation. Studies of Federal Aviation Administration (FAA) seat tests were used to form the basis of a computer analysis to address …

Lumen Air : “the day I started an airline”
… mockup that more accurately represented an aircraft cabin, including details such as overhead bins and reading lights, with full cabin service. Each of the flights was accompanied by a surround sound soundscape from takeoff to landing with full cabin service including five-course meals, …

The Control of Interior Cabin Noise Due to a Turbulent Boundary Layer Noise Excitation Using Smart Foam Elements
… a smart foam actuator in controlling interior cabin noise due to a turbulent boundary layer excitation has been experimentally demonstrated. A smart foam actuator is a device comprised of sound absorbing foam with an embedded distributed piezoelectric layer (PVDF) designed to operate over a …

The development of a systems design model for job performance aids : a qualitative developmental study
… design model for use by corporate aviation cabin crewmembers. The procedural design model was then validated by comparing the performances of an experimental group and a control group of professional cabin crewmembers who conducted an emergency procedure in an aircraft cabin simulator. The …

The evaluation of the 90 second certification test and the analysis of human behaviour within aircraft evacuation modelling
The majority of fatalities during an aircraft accident occur after impact with approximately 95% due to burns and smoke inhalation due to sub optimal evacuations. If post-crash survivors can be evacuated quickly enough then the survival rate could be improved. This thesis will examine the influence …

Modeling person-to-person contaminant transport in enclosed environments
… in an office mockup and the first-class cabin of a functional MD-82 aircraft. The experimental data of steady-state airflow, temperature, and gas contaminant concentration fields obtained in the office were used to validate the steady-state computational fluid dynamics (CFD) models. In …
