Development, Testing and Calibration of Oxford Brookes V-Twin Engine
… or competition vehicle. For over a decade, the V-Twin project aimed to provide a superior powertrain package for the Formula Student entry of the Oxford Brookes team, as a flagship for the capabilities and commitment of the students involved. This research built on the thousands of hours already …

An Alternative Method of Identification of a Failed Engine in Twin-Engine Propeller Aircraft
… revealed that wrong identification of a failed engine during flight is not an uncommon event in an aircraft cockpit. A number of fatal accidents in the past, including the recent TransAsia Flight 235 accident, resulted from engine misidentification. Most accidents of this type happened on …

Reliability analysis of the electrical system in Boeing 757-200 aircraft and RB211-535 engines
… severe consequences of system failure. In 1953, twin-engine aircraft were restricted to fly on routes that were within 60 minutes from an alternate airport. In 1985 the Extended Twin-engine Operations (ETOPS) rules were established. They are a deviation from the 60 minute restriction, allowing …

Effectiveness of adaptive flight planning in the occurrence of total loss of thrust due to bird strike
… 96 percent of air travelers are transported on twin-engine jets. Although contemporary twin-engine jets are more reliable and efficient than yesterday’s three- and four-engine jets, they have reduced engine redundancy. A statistical analysis of the FAA Wildlife Strike Database shows that …

Preliminary investigation of light scattering and visibility in two eastern national parks
… air quality related parameters were mounted in a twin engine light aircraft. Data obtained from horizontal and vertical profiles flown in the two parks on six days between April and June 1979 were utilized in this study. However, these data are not conclusive in that sampling flights were …

Modeling and simulation of commercial aircraft electrical systems
… modeled was that of the Boeing 737, a typical twin-engine aircraft. Aside from the components that were modeled, the various simulations were performed using a sample flight profile of an aircraft, which details parameters of flight over time, and an engine model developed in Numerical …

Evaluating Scenarios That Can Startle and Surprise Pilots
… had on commercial pilots with single and multiengine ratings. Surprise is defined here as something unexpected (e.g., engine failure), while startle is the associated exaggerated effect of an unexpected condition (e.g., thunder sound). Forty pilots were tested in a basic aviation training …

Examination of Runway Occupancy Times for General Aviation Aircraft
… II aircraft. For aircraft categories, single engine propeller driven aircraft that weigh less than 12,500 pounds are category I aircraft; twin engine propeller driven aircraft weighing less than 12,500 pounds are category II aircraft (Federal Aviation Administration, 2009). All other aircraft …

Range and endurance modelling of a multi-engine aircraft with one engine inoperative (oei)
When one of the engines on a multi-engine aircraft stops working the one engine inoperative (OEI) condition exists. This causes several negative effects to a number of performance variables in addition to the loss of engine thrust. The range and endurance of an aircraft are directly related to the …
