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...
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 ...
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...
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 through the vehicle attitude. The angle of attack modulates the force magnitude and the loads applied to the vehicle. The bank angle...
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

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 ...
For air, the monetary cost includes the flight and access/egress fares between the airport and the central stations of the cities. For car, we assume that travel time is 1.2 times longer in peak periods than in off-peak periods due to congestion (assessed by using Google maps). For other...
