ASSOCIATION OF ROCKETRY LEVEL 2
HIGH POWER CERTIFICATION STUDY
GUIDE) 100 QUESTIONS WITH CORRECT
SOLUTION!!
1 of 100
Term
A rocket's center of pressure can be estimated by using:
The "Barrowman" method
Finding the point where the model balances
The "cardboard cutout" method
Both "A" and "C" above
Give this one a try later!
, D) Both "A" and "C" above D) Both "A" and "C"
A) Temperature cycling D) Both "A" and "B" above
Don't know?

Term
What is a common safety practice to follow just before hooking up
the igniter leads to a rocket?
A) Touch the igniter clips together to test for sparks in case the
launch system is still accidentally energized
B) Run an additional simulation to ensure the rocket and motor are
a safe combination
C) Check the skies to ensure no aircraft are in the area
D) Stand next to the rocket for a photograph
Give this one a try later!
A) Touch the igniter clips
together to test for sparks in B)This hole is used to sample
case the launch system is air pressure readings outside
still accidentally energized the rocket's airframe
C) No, the five-tenths coverage and B) Launch rails are stiffer and
horizontal visibility limitations apply less likely to impose unintentional
tipoff on the rocket (no rod
whip)
, Don't know?

Term
Which of the following individuals has the ultimate responsibility to
ensure that a rocket was built in a safe manner?
A) The Launch Control Officer (LCO)
B)The Range Safety Officer
C) The rocket owner/builder
D) All of the above
Give this one a try later!
B) The Range Safety Officer (RSO) C) The rocket owner/builder

4 of 100
Term
As a rule of thumb, how far should the center of pressure be from
the center of gravity?
A) The center of pressure should be at the same location as the
center of gravity
B)The center of pressure should be at least 1.0 body tube diameters
, behind (aft) the center of gravity
C) The center of pressure should be at least 1.0 body tube
diameters ahead (forward) of the center of gravity
D)The center of pressure should be 1.0 body tube diameters
ahead (forward) of the fin leading edge; the center of gravity does
not
matter
Give this one a try later!
A) Touch the igniter clips
A) 100 feet
together to test for sparks in case
the launch system is still
accidentally energized
B)The center of pressure
should be at least 1.0 body B)The total impulse is more than 160
tube diameters behind (aft) Newton-seconds
the conter of gravity
