Results from three months of simulated flight routes between London and New York show that permitting optimised en-route airspeed variations leads to fuel savings of 0.5% on an average day (and up to 4% on certain days), compared with fixed airspeed flights. We conclude that significant fuel ...
With the advent of improved aircraft situational awareness and the need for airlines to reduce their fuel consumption and environmental impact whilst adher
A straightforward formula is frequently used in engineering practice (Dong et al., 2021), which leaves out airspeed and air humidity, and is as follows: (14)where is the average temperature of the skin surface, which is 33.5 °C, is the indoor temperature, M is the metabolic rate of ...
to compare it to the same array obtained in the vicinity of the minimum, the results of comparing the determined wholesale mal airspeed corresponding to the border of a statistically significant difference compared arrays, and converted to an aircraft in flight mode with maintaining optimal speed. ...
The initial conditions are calculated for any external condition (airspeed, irradiance, temperature), considering the case in which the temperature profile in the walls follows a hysteretic cycle. This cycle oscillates around the set-point air temperature following the refrigeration ON/OFF cycle. ...
As it is known, winged aircraft require relative airspeed to remain airborne, and this creates the need for engines and the energy to feed them for the duration of the flight. This in turns limits the weight onboard which can be used for payload. Furthermore, the need for aircraft to ...
