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...
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 ...
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 ...
This is the natural train of thought for the engineers, who understand what kinds of things might cause the autopilot to disengage. For the pilots, it was not the case. They forced the aircraft into a steep upward climb, ignoring the “STALL” warnings, until it lost all airspeed and plum...
(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...
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...
factors. The quality of the turn is measured by the pilot's ability to determine when to begin rolling the wings level, when to stop at level and most of all how to keep it there during the transition. For every degree of bank and airspeed we must learn what to do and when to do ...
stall speed will be lower. This accounts for the book differences you should have noted.The way an aircraft behaves entering, during, and recovering from a stall is used to determine its stall characteristic.These characteristics are determined at the aft CG when stall speed is at its slowest....
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...
