The feasibility of using a stand alone Fluidic Thrust-Vectoring (FTV) system for the purpose of longitudinal trim of an unmanned aerial vehicle is the focus of the research presented in this paper. Since the fluidic thrust vectoring requires high pressure secondary air to deflect the engine exhaust gases, this research also provides an analytical toolset for preliminary sizing of a suitable sec...

Fault detection and isolation (FDI) logic plays a crucial role in enhancing the safety and reliability, and reducing the operating cost of aircraft propulsion systems. However, it is a challenging problem achieving the FDI task with high reliability. For this purpose, various approaches have been proposed in the literature. In an on-line engine fault diagnoses, two tasks may use Kalman filter t...

The article investigates the strength of propeller blades made a multilayer composite material, subjected to centrifugal and gas loads with various combinations fiberglass carbon fiber orientation material base. finite element method is used as research method. A blade in turbines jet engines compressors, materials, considered naturally twisted rod, provided that hypothesis flat sections across...

We report selected carbon species emission indices (EIs) for a Rolls Royce RB211-535-E4 turbofan engine that were acquired during the NASA EXperiment to Characterize Aircraft Volatile Aerosol and Trace-species Emissions (EXCAVATE). Conducted during winter 2002, the mission focused upon characterizing the exhaust constituents of the NASA Boeing 757 aircraft during ground-based operation. Carbon ...

As our society becomes more technologically complex, computers (and the software that they run) are being used in a potentially alarming number of high consequence safety-critical applications. When these systems fail, the outcome can be devastating. For example, several years ago a British Midland 737 aircraft crashed killing 47 people and seriously injuring 74 others. The reason for the crash...

As aircraft continue to increase their power and thermal demands, transient operation of the power and propulsion subsystems can no longer be neglected at the aircraft system level. The performance of the whole aircraft must be considered by examining the dynamic interactions between the power, propulsion, and airframe subsystems. Larger loading demands placed on the power and propulsion subsys...
