To ensure flight safety, extensive flight-testing and active structural servo control strategies are required to explore and expand the boundary of a flight envelope. Aeroservoelastic (ASE) models can provide online flight monitoring of dynamic instabilities to reduce flight time testing and increase flight safety. The reliability of an ASE model for the flight envelope prediction and flight sa...

Fatigue has been a long-standing concern in modern aviation. The duty hours of those who operate (cabin crew and pilots) have increased significantly. In order to combat the effects fatigue, operators must adhere Flight Time Limitations (FTLs) strictly set by regulatory bodies. With advances science European Aviation Safety Agency (EASA) February 2016 altered limits rest periods. A quantitative...

The flight potential and metabolism of two malaria vectors, Anopheles gambiae s.str. and An. atroparvus, were analyzed on flightmills. The flight distance, the flight time, and individual flight activities of females were recorded during 22 h flight trials. The glycogen and lipid before flight, after flight, and of unflown controls were measured for starved, sugar-, or blood-fed females. Maxima...

More often than not, airlines use aircraft in operating scenarios beyond their optimal design conditions, which negatively affects performance characteristics. These effects are statistically reflected flight operational data, indirectly constrained by air transportation management as well design. In this research, we develop a data-enhanced methodology for modeling dynamic simulations of to en...

This paper proposes a technique for planar trajectory following for an autonomous aerial robot. A trajectory is modeled as a planar spline. A behavior-based control system which stabilizes the robot and enforces trajec-tory following, has been implemented and tested on an autonomous helicopter. Results from two ight experiments are presented. The trajectory tracking error is on the order of the...

Bats evolved the ability of powered flight more than 50 million years ago. The modern bat is an efficient flyer and recent research on bat flight has revealed many intriguing facts. By using particle image velocimetry to visualize wake vortices, both the magnitude and time-history of aerodynamic forces can be estimated. At most speeds the downstroke generates both lift and thrust, whereas the f...
