Formulas
Formula for Speed
What is distance traveled over amount of time traveled. S=D/T
Also known as the UH 60
What is the Black Hawk?
In the tail rotor, the anti torque pedals control this
What is pitch & thrust of the tail rotor blades?
NOE is also known as
What is NAP of the Earth? Conducted at varying speeds as close to the Earth's surface as vegetation and obstacles permit.
This is controlled by pedals
What is heading, direction of turn, and rate of turn at a hover
Formula of Power
What is power = work over time. P= w/t
What is the Bell TH 67?
Ratio of the total rotor blade area to the total rotor disk area
What is Solidity Ratio
Most favorable conditions to fly
What is low density altitude, light gross weight, and moderate to strong winds.
This changes the rotational pitch of rotor blades
What is Cyclic
Formula for Displacement
What is Displacement = final position - original position
The primary use of this aircraft include air assault and air movement. Can drop 2000 galloons of water during water bucket operations
What is Chinook (CH 47)
This happens when you press one of the pedals of the tail rotor
What is changes the pitch of the tail rotor, altering the amount of thrust being used?
With the collective, the pilot is in control of this
What is angle of the main rotor blades and engine RPMs
This is how blade rotation creates lift
What is Laminar flow of air molecules generate a low pressure area above the rotating airfoils relative to under.
Formula for Mass
What is mass = force over acceleration.
This aircraft conducts distributed operations, precision strikes against relocatable targets, and provides armed reconnaissance.
What is Apache Longbow (AH 64)
Transcient torque occurs at this moment
What is when lateral cyclic is applied. Single main rotor only!
BONUS !
Please see Mitty for the bonus stack of cards.
Vertical distance of the aircraft above mean sea level
What is True Altitude
Formula for Work
What is Work = force X displacement. W = F x d
This aircraft serves the Army principally for logistics and support missions within the US. It is also used by the Army National Guard for homeland security and disaster-response missions and medical evacuations.
What is the Lakota (UH 72A)
In a vertical autorotative decent in still air, the forces that cause the blades to turn are:
What is similar for all blades regardless of their position in the plane of rotation making dissymmetry of lift NOT a factor.
This conditions tend to lessen a helicopter's performance
What is high altitude, high temperature, high moisture (high density altitude).
When AOA is increased, this happens
What is greater acceleration over the top of the airfoil. Larger differential between top and bottom of airfoil.
