Performance and wake analysis of rotors in axial flight using computational fluid dynamics [PDF]
, 2017 Flow field around rotors in axial flight is known to be complex especially in steep descent where the rotor is operating inside its own wake. It is often reported that, in this flight condition, the rotor is susceptible to severe wake interactions ...

Modeling of the Flight Performance of a Plasma-Propelled Drone: Limitations and Prospects
DronesThe resurgence in interest in aircraft electro-aerodynamic (EAD) propulsion has been sparked due to recent advancements in EAD thrusters, which generate thrust by employing a plasma generated through electrical discharge.

, 2021 In this chapter, the problem of flight vehicle performance is described. Performance parameters, such as lift-to-drag ratio, maximum and minimum level flight speed, speeds for the best rate of climb, steepest climb, maximum range and endurance, and most economical climb are described using graphical methods, such as drag polar, Zhukovsky curves with ...

Calculating Launch-Vehicle Flight Performance Reserve [PDF]
Journal of Spacecraft and Rockets, 2011 This paper addresses different methods for determining the amount of extra propellant (flight performance reserve or FPR) that is necessary to reach orbit with a high probability of success. One approach involves assuming that the various influential parameters are independent and that the result behaves as a Gaussian.

Data-enhanced dynamic flight simulations for flight performance analysis
Aerospace Science and Technology, 2022 More often than not, airlines use aircraft in operating scenarios beyond their optimal design conditions, which negatively affects their performance characteristics. These effects are statistically reflected in flight operational data, which are indirectly constrained by air transportation management as well as aircraft design.

Flight experience and executive functions predict unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA) [PDF]
, 2010 Unlike professional pilots who are limited by the FAA's age rule, no age limit is defined in general aviation (GA). Some studies revealed significant aging issues on accident rates but these results are criticized.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

The development of compensatory ability for a sexually-selected ornament in stalk-eyed flies
Frontiers in EthologyFemale preference for longer eyespan has driven exaggerated sexual dimorphism in several species of stalk-eyed flies. Longer eyespan increases a fly’s moment of inertia, and flies experience significant increase in body mass across age as they mature ...
