What does a vortex generator aim to do (scientifically)
How do vortext generators do this
Benefits of vortex generators
Air aircraft of a certain weight is flown at 150kt IAS at 1000ft. If the same AC was flown at 150kt ISA at 20,000ft, the angle of attack req to maintain level flight would be
devises such as slats, slotted flaps and vortex generators act to modify the behavior of the
compared with nil wind conditions, a headwind component during cruise will
to achieve max range when a head or tail wind exists, the correct speed to use is
for two AC, identifical in every aspect f apart for gross weight, to achieve max range in nil conditions
Refer to qn 6. To use the least amount of fuel in a given distance for nil wind conditions, the ac must be flow
ignoring all other considerations, the theoretical heigh to fly a piston engine ac to achieve max range is
for an ac at a particular gross weight to maintain level flight at a particular height and IAS, a particular power setting is reqd. If gross weight is increased....
When flap is lowered on an aircraft in flight,
An ac is in straight and level flight at constant power. As weight reduces with fuel burn-off, level flight may be maintained by
Considering an aircraft maintaining straight and level flight at the speed which produces maximum endurance. If level flight is to be maintained,
In the lift equation, S represents
In the lift equation, p represents
The term 1/2pV^2 in the lift equation is most closely associated with
