…tabulates their energy consumption as a function of weight, velocity, flight times and costs (chart above). The equations of flight are then modeled out fully for Amazon’s Prime Air concept…
…turbines’ nacelle can be used to measure wind direction (and strength), however, it is difficult to obtain accurate readings in the turbulent air behind rotor blades. LiDAR can be measured…
…via the Brayton Cycle, compressing inlet air, super-heating it to 1,200-1,600ºC by combusting a gaseous fuel, then expanding the super-heated gas mixture across a turbine. The turbine can be used…
