I've been contemplating this question: at what air speed can the I2 cover the most distance on a set of full batteries. For this theoretical question, we can assume no wind, level, straight flight. This could translate to a more practical question: if I'm running low on battery, what...
These values were shown to allow efficient convergence across all wind fields considered. Given the time restriction on trajectories, the fixed airspeed yielding the minimum fuel use will depend on the daily wind field. For this reason, fuel use for trajectories flown at all airspeeds in ...
Finally, diversified allocation strategies such as adjusting flight paths, flight speeds, and flight times are designed. Based on the multi-strategy self-adaptive configuration, an optimization and allocation model is established. The optimization performance and parameter sensitivity of the proposed method...
In all scenarios tested, the direction selectivity of collision-free maneuver can be successfully integrated into the DORCA algorithm, and the algorithm is more efficient than the ORCA algorithm for collision avoidance in decentralized way. Introduction With the increasing of airspace density, more ...
For the trajectory generation process, three ball models will be used to determine the table tennis task constraints (2)–(4): ball flight model, ball–table rebound model and ball–racket contact model. Whenever an incoming ball is detected in midair, a flight model will first be used to...
The most stringent constraint comes from the convection flux that grows quickly when entering the dense atmosphere layers at hypersonic speeds. A near-horizontal flight is mandatory to achieve a progressive braking at limited thermal flux and load factor levels. The aerodynamic forces are controlled ...
We then compared the upwind speeds of moths tested with flower plumes with those of moths tested with an empty control. Nectar analyses and net-energy calculation. The energetic outcome of the moth foraging flight is affected by the moth's energy invested and the energy gained through the ...
Tracking odour trails is a crucial behaviour for many animals, often leading to food, mates or away from danger. It is an excellent example of active sampling, where the animal itself controls how to sense the environment. Here we show that rats can track odour trails accurately with near-o...
Fig. 19. Drone with a helix type trajectory for achieving high speeds in descent. By following the helix type trajectory, the quadcopter can achieve high descent speeds considering the VRS and WBS constraints on air stream velocities in the blade disk frame. The conclusions obtained with these ...
Cost efficient foraging is of especial importance for animals like hawkmoths or hummingbirds that are feeding ‘on the wing’, making their foraging energetically demanding. The economic decisions made by these animals have a strong influence on the plan
