Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
Apply opposite aileron to the direction of the roll.
What is a VOR? What frequency range and band is it in?
What is a VOR? What frequency range and band is it in?
VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.
VOR's are assigned radio channels between 108.0 MHz and 117.95 MHz (with 50 kHz spacing); this is in the very high frequency (VHF) range.
How does a jet engine/gas turbine work?
How does a jet engine/gas turbine work?
Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).
Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.
Why do some airplanes have dihedral wings?
Why do some airplanes have dihedral wings?
Dihedral provides:
Lateral stability (during a roll) Wing clearance, wingtip to ground has more space
