The CYPRES computer takes a measurement of air pressure on the ground and uses this to determine the skydiver's altitude throughout the day. Whenever the skydiver is on the ground, the unit recalibrates every 30 seconds to handle weather-based changes in atmospheric pressure. Getting Into Sky...
modeled by introducing a whole series of connected intermediate nodes and running a shortest-path algorithm to determine the best route to get between distinguished nodes (the cities); this also allows one to model there being different speeds for take-off and for landing and for cruising. And ...
This pattern is reviewed on readout to determine if any of the data has been damaged by crash impact, fires or pressure. There are several tests that make up the crash-survival sequence: Crash impact: Researchers shoot the CSMU down an air cannon to create an impact of 3,400 Gs (1 G...
Understand each element of the lift equation. L signifies lift force, measured in Newtons; ρ signifies air density, measured in kilograms per cubic meter; v2signifies true airspeed squared, which is the square of the speed of the helicopter relative to the oncoming air, expressed in meters per...
Besides the engines’ power, the plane’s aerodynamic design allows the plane to slice through the air with ease. Generally speaking, the more aerodynamic and powerful a plane is, the faster it can potentially fly. How Fast Do Planes Fly in Different Situations Many factors determine an ...
you must conduct studies to determine the thought patterns that they induce in users and adjust as necessary. When you test your new systems, you must test them with real users in real environments under realistic conditions. And unfortunately, when you alter your designs, you must do these st...
we can then determine the pressure forces and thus lift. If we do a simple calculation we would find that in order to generate the required lift for a typical small airplane, the distance over the top of the wing must be about 50% longer than under the bottom. Figure 1 shows what such...
(IFR) would apply, even if visual separation was used as a backup in VMC. That is not to say Europe is right and America is wrong. Each State has a right to decide what level of risk it finds acceptable, and to determine ways of ensuring that its agreed standards are met, in the ...
For each type of battery, we’ll determine: How many batteries required to power up the engines to reach takeoff speed (assuming that it takes a minute to do so) How many would be in the airplane if we swapped fuel with batteries (assuming no volume restrict...
Since this is an unknown parameter in this study, we defined a reference SWT at 12.8 °C to determine the steady-state design capacity used to calculate V̇tlt. However, we maintained the same calculated V̇tlt for each test case throughout the iteration process of finding the final SWT...
