what is the difference between G10 and G12 fiberglass
G10 is more rigid (flat sheets) and used for the fins, G12 is the wound tube used for the airframe (difference is in the manufacturing)
200
what does ISP measure
the efficiency of a rocket motor to product thrust from propellant
200
what type of controller was used for the airbrakes on magnolia
PID (proportional integral derivative)
200
what were the magnolias simulations written in
python
200
8th planet from the sun
neptune
300
how tall was magnolia (in inches)
92 inches (technically 91.5)
300
what is the difference between thrust and total impulse
thrust is an instantaneous force, total impulse is thrust integrated over time
300
what is the process of framing telemetry data for transmission and receiving
commutation/decommutation
300
what does the force of drag on a body depend on (4 things)
cd (coefficient of drag), surface area, velocity, and fluid density
300
how many calories does 1 cup of whole milk have (you have a range of plus or minus 10 calories)
150 kcal
400
what does a coupler do
join 2 sections of the airframe (slides together) while keeping the body as 1 continuous piece
400
what is the purpose of converging-diverging geometry of nozzles
accelerates the exhaust gas and converts pressure/thermal energy to kinetic energy
400
what communication protocol was used to communicate with the airbrakes
Dshot (technically pwm also counts)
400
what is FSI
fluid-structure interaction: coupled workflow for structural/fluent sims that feeds data back and forth
400
name one of the founders of Palantir
peter thiel
500
what is a load path and why is it important
determines how forces get transferred and prevents structural failure (CATO)
500
what happens to thrust if the mass flow rate of the exhaust increases but exhaust velocity is constant
thrust will increase
500
what frequency and bandwidth did the magnolia radio operate at
900 MHz (33cm) at 650kHz
