Rockets Flashcards
types of chemical propellants
solid, liquid, semi-solid, gelled
**most common
oxidation
the reaction of oxygen with another substance
oxidizer-oxygen used in pure form of fuel
reducers-fuels other than oxygen (hydrogen, carbon, nitrogen)
must be chilled till liquid
combustion for propulsion
key factor-how much force can be obtained
must contain oxidizer and reducer
ignite correctly
energy in a form of force and controllable
ignition characteristics
repeatedly started and stoped?
require during all the propellant (burnout)
pressure and mass flow
pressure heats it up
engine is container for temperature
mass flow out nozzle for thrust and propulsion
solid propellants
The fuel and oxidizer of a solid propeller mixed together
Burn until exploded
liquid propellant
monpropellant systems- oxidizer in fuel in one solution
Bipropellant-oxidizer and fuel are separated 
hybrid propellant
liquid and solid repellent systems
Solid material as fuel and liquid as oxidizer most common
flexibility 
history of rockets
first in china
then russian first into space
U.S. dr robert goddard
newton’s laws of motion
A body rest stays at rest and less acted upon by another force
Rate of change in the momentum of a body portal to the force acting upon it
to every action there’s an equal and opposite reaction
specific impulse isp thrust
The number of pounds of thrust delivered by consuming 1 pound of repellent in one second
density impulse sap
The measurement of a propelled rest according to its volume
types of orbits
circular- requires injection volcity
elliptical- one shot if angle is correct
layers of the sun
photosphere- give light
chromosphere- sphere of color
corona- crown
solar system in order
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
the space race
soviet union vs us
sputnik
us focused on precision. su focused on power
space law
how to govern space
treaties- three principles of space
what are the three principals of space
1: freedom of use
2: non-appropriation
3: common interest
treaties
- tpaseuos- outer space treaty
addresses emergency landing - ABM: anti ballistics missile treaty
five programs of manned space flight
- project mercury- get man to space
- project gemini- prepare for mission to moon
- project apollo- put man on the moon
- project skylab- put laboratory in space
- project apollo soyuz- international space effort
6?. space shuttle- reusable space vehicle
