Rockets

Question 1

types of chemical propellants

Answer 1

solid, liquid, semi-solid, gelled
**most common

Question 2

oxidation

Answer 2

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

Question 3

combustion for propulsion

Answer 3

key factor-how much force can be obtained
must contain oxidizer and reducer
ignite correctly
energy in a form of force and controllable

Question 4

ignition characteristics

Answer 4

repeatedly started and stoped?
require during all the propellant (burnout)

Question 5

pressure and mass flow

Answer 5

pressure heats it up
engine is container for temperature
mass flow out nozzle for thrust and propulsion

Question 6

solid propellants

Answer 6

The fuel and oxidizer of a solid propeller mixed together
Burn until exploded

Question 7

liquid propellant

Answer 7

monpropellant systems- oxidizer in fuel in one solution
Bipropellant-oxidizer and fuel are separated 

Question 8

hybrid propellant

Answer 8

liquid and solid repellent systems
Solid material as fuel and liquid as oxidizer most common
flexibility 

Question 9

history of rockets

Answer 9

first in china
then russian first into space
U.S. dr robert goddard

Question 10

newton’s laws of motion

Answer 10

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

Question 11

specific impulse isp thrust

Answer 11

The number of pounds of thrust delivered by consuming 1 pound of repellent in one second

Question 12

density impulse sap

Answer 12

The measurement of a propelled rest according to its volume

Question 13

types of orbits

Answer 13

circular- requires injection volcity
elliptical- one shot if angle is correct

Question 14

layers of the sun

Answer 14

photosphere- give light
chromosphere- sphere of color
corona- crown

Question 15

solar system in order

Answer 15

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto

Question 16

the space race

Answer 16

soviet union vs us
sputnik
us focused on precision. su focused on power

Question 17

space law

Answer 17

how to govern space
treaties- three principles of space

Question 18

what are the three principals of space

Answer 18

1: freedom of use
2: non-appropriation
3: common interest

Question 19

treaties

Answer 19

1. tpaseuos- outer space treaty
   addresses emergency landing
2. ABM: anti ballistics missile treaty

Question 20

five programs of manned space flight

Answer 20

1. project mercury- get man to space
2. project gemini- prepare for mission to moon
3. project apollo- put man on the moon
4. project skylab- put laboratory in space
5. project apollo soyuz- international space effort
   6?. space shuttle- reusable space vehicle
