Solid Propellant Rockets
These were the first true rockets.
What are Fire Arrows?
The upper ends of the Space Shuttle Solid Rocket boosters are what?
What is a star shaped core?
A rocket engine does not need an ignition system if it has this.
What is hypergolic propellants.
These were ineffective in old rockets.
What is launch rods?
Electric rockets have been around since.
What is the 1960's
The propellant in solid rockets is packed inside this.
What is the insulated case?
These were ignited with a fuse.
What are Chinese Fire Arrows?
These two items together ignite spontaneously.
What is Monomylhydrozene (fuel) and nitrogen tetroxide(oxidizer)
These were launched by the thousands so at least a few would hit there targets.
What is Military Rockets?
Driven out of the rocket engine using magnetic forces.
What are electrically charged atoms?
accomplished by attaching a long stick to create drag as a rocket sailed through the air.
What is Flight Control?
Solid Propellant rockets have two major systems at work.
What is the control center and the igniter.
Two items mix as they are sprayed into the chamber.
What is the fuel and oxidizer mix?
accuracy for rockets improved when these were added to the exhaust stream.
What is small vanes?
Functions continuously for months or years on end.
What is ion drive?
Very large tubes packed with propellants that are closed at one end and have a hole at another.
What is solid Rocket boosters
These were used for centuries until they were replaced with this.
electric ignition
This forces the propellants into a cylindrical or spherical combustion chamber.
What is high speed pumps?
This imparted stability by causing the rockets to spiral like bullets.
What are the vanes.
electric rockets are referred to as.
what is Ion drive?
The propellants burn much more rapidly because the entire face of the core is ignited at one time.
What is a hollow core.
A wire with high resistance heats and ignites the propellant.
What is an electric system.
These type of engines have a number of advantages over solid propellant engines.
What is liquid propellant engines.
A pivoted support that allows a body to rotate around a single axis passing through the pivots
What is a gimbal
What does the Acronym NASA stand for.
