True air speed (VTAS) is the actual speed of the aircraft relative to the air. It is evaluated by multiplying VEAS by the square root of relative density as presented in Figure 19-4. This correction is due to the fact that the density of air at sea level is embedded in the probe ca...

Although RAVEN is still able to transition to flight mode using falling and standing take-offs, these two strategies have underperforming take-off speed and time duration, and height and distance gain compared with those for jumping take-off. Supplementary Video 6 Forward hop and height jump. ...
(15.26) that gust damage increases in proportion to Ve5.26, so that increasing forward speed has a dramatic effect on gust damage. The total fatigue damage suffered by an aircraft per flight is the sum of the damage caused by the ground–air–ground cycle, the damage produced by gusts, ...
Lateral CH4 inputs to Arctic lakes through groundwater discharge could be substantial and constitute an important pathway that links CH4 production in thawing permafrost to atmospheric emissions via lakes. Yet, groundwater CH4 inputs and associated drive

(Gonçalves et al.2017). The major benefit of implicit modeling relies on its speed, which allows faster assessments of new information and uncertainty simulations, accordingly reducing the intrinsic risks of geological modeling (Cowan et al.2003; Wellmann et al.2010; Birch2014; Vollgger et al...
(Abramowski2007). In the latter case, a Venturi nozzle is generated between the foil and the ground, so the negative lift is due to the Bernoulli effect. This effect is used by race cars and is caused by the Venturi nozzle between airfoil and ground, where high-speed low-pressure air ...
The speed is essentially the same for all frequencies of sound, but the speed does depend on the pressure and the density of the air. At an altitude of 40 000 ft or 12 km (where many jetliners fly), the pressure and density conditions are such that the speed of sound is about 13 ...
wind speed, net radiation, and evapotranspiration are 80%, 21.39 °C, 29.94 °C, 1.32 ms-1, 10.44 MJm-2 day-1, and 3.72 mmd-1, accordingly. Western Bangladesh is drier than other regions. Agriculture in Bangladesh heavily relies on groundwater irrigation, primarily for growing staples such...
