Igniter - Study guides, Class notes & Summaries

AMP 221 TURBINE THEORY FINAL EXAM STUDY GUIDE When an engine with a subsonic divergent type inlet duct is running in place at high speed on the ground, the air pressure within the inlet is Positive What will result if an oil filter becomes completely blocked? Oil will flow at the normal rate through the system. Why are turbine engine igniters less susceptible to fouling than reciprocating engine spark plugs? The high-intensity spark cleans the igniter. For what primary purpose is a turb...

ROCKET AND MISSILES UNIT I 1. What are the types of igniters? Gaseous igniter Liquid igniter Solid igniter 2. Define gaseous igniter. The propellants used in the ingniter are of gaseous state. Reaction gaseous mixture stored in a very thin tube with high pressure. Hazardous in nature. Used only for space application. 3. Write down the characteristics of hypergolic liquids with example. Very high bulk density. Chemically stable. Low vapour pressure. Good heat transfer ch...

using an ohmmeter, there is 120 VAC between high speed and ground wires, this indicates : open if temperature rise is too high... : increase fan speed how many of the 3 OSHA conditions defining confined spaces must be met : all 3 what causes the temperature limit safety switch to shut off the burner : fan motor failure flashback indicates : the gas is flowing slower than the speed at which burn is occurring what type of connector is used to control noise in ductwork 2 | P a g e : v...
