Wind Tunnels
Horsepower per fan in a two-loop system
What is 200 horsepower?
This force increases as an object falls through air
What is drag (or air resistance)?
The basic word to describe any push or pull
What is a force?
Two variables of terminal velocity that vary from person to person
What are mass and frontal area?
Protects the eyes during flight
What are goggles?
Maximum speed of the air in our wind tunnel
What is 165 mph?
This force remains constant throughout a skydive
What is force of weight (mass x gravity)?
The portion of an object that the wind can push
What is frontal area?
The relationship between mass and terminal velocity
What is positive (or directly) related?
Protects your hearing while in the wind tunnel
What are earplugs?
Type of system where air is recirculated
What is closed loop?
The dominant force acting on a skydiver when they exit the aircraft
What is force of weight (gravity x mass)?
When the forces of gravity and drag (air resistance) are equal, and when the acceleration of the object equals zero
What is terminal velocity?
The relationship between frontal area and terminal velocity
What is negative (or inversely) related?
Reason the flight suit should fit big/baggy
What is to increase drag/air resistance?
Purpose of turning vanes
What is create smooth air flow?
The dominant force acting on a skydiver when the parachute first opens
What is force of drag (air resistance)?
The effect mass has on an object's velocity when falling through a vacuum
What is none?
Air density's relationship to terminal velocity
What is negative (or inversely) related?
Spring loaded and made of steel
What is the safety net?
Purpose of inlet contractor
What is increase air speed?
A head down orientation during free fall will have this affect on a skydiver's velocity
What is increase?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is Newton's First Law of Motion? or Law of Inertia?
9.81m/s2
What is acceleration due to gravity?
12 seconds
What is the approximate duration of lift remaining if all fans stop spinning?
