CAUTION: The high energy level and voltage associated with turbine ignition systems can cause injury or death to personnel coming into contact with the activated system. Tighten and secure as required and replace faulty components and wiring. Secure, tighten, and safety as required.
What cautions should be taken with ignition systems and why?
Keep these 8 safety precautions in mind when working with ignition systems.
- Always wear OSHA-approved safety glasses when. …
- When working on any ignition system when the. …
- Never use your hands to pull high-tension wires. …
- When replacing parts or doing other work on the. …
- Always use the correct tools when working on.
What is turbine engine ignition system?
Most aircraft engines rely on an electrical ignition system to create a spark, which in turn initiates or continues the engine’s combustion process. … The function of gas turbine ignition systems is to convert energy from some source to a high intensity electrical discharge (i.e., sparks).
What are the three primary components of a turbine engine ignition system?
There are three components of a turbine engine ignition system: the exciter, the ignition lead, and the igniter. The exciter takes input current from the aircraft electrical system, steps up the voltage, and delivers a high voltage output signal through the ignition lead to the igniter.
Why are turbine engine igniters generally not susceptible to carbon fouling?
Why are turbine engine igniters less susceptible to fouling than reciprocating engine spark plugs? The high-intensity spark cleans the igniter. the construction is such that the spark occurs beyond the face of the combustion chamber liner.
What are the three types of ignition system?
There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP).
Why is it important to study about the ignition coil?
If you drive with a faulty ignition coil, the fuel will not combust properly in the chambers. This will lead to the following. Loss of gasoline through the exhaust, which leads to your car backfiring.
What is meant by a shrouded turbine?
The shrouded tidal turbine is an emerging tidal stream technology that has a turbine enclosed in a venturi shaped shroud or duct (ventuduct), producing a sub atmosphere of low pressure behind the turbine. … Claimed improvements vary, from 1.15 to 4 times higher power output than the same turbine minus the shroud.
How are turbine engine ignition systems rated?
What are turbine engine ignition systems rated in? Joules (watt-seconds). Why are igniters needed? They need to produce a spark intense enough to vaporize and ignite the fuel (Jet Fuel – kerosine, harder to ignite compared to AVGAS).
How many igniters are used in most turbine engines?
5. How many igniters are there normally in an aircraft turbine engine? Two.
What type of ignition system is used on gas turbine engines?
MODERN CAPACITOR TYPE
The high-energy, capacitor-type ignition system has been universally accepted for gas turbine engines. It provides both high voltage and exceptionally hot spark which covers a large area. Excellent chances of igniting the fuel-air mixture are assured at reasonably high altitudes.
Which two types of igniter are used on gas turbine engines?
There are two types of igniter plugs; the constricted air gap type commonly used on gas turbine engines and the shunted surface discharge type. As the name implies, the air gap type has a larger gap between the body of the igniter and the electrode.
What is the difference between a low tension and a high tension ignition system?
What is the difference between a low tension and a high tension engine ignition system? … A low-tension system uses a transformer coil near the spark plugs to boost voltage, while the high tension system voltage is constant from the magneto to the spark plugs.
What can cause ignition problems?
Worn ignition switch contacts, temperature problems, or broken springs can all cause the ignition switch to fail, preventing you from starting your car. On the road, poor ignition switch contacts could shut the engine off while driving, which could be dangerous.
At what RPM is a reciprocating engine ignition switch check made?
At what RPM is a reciprocating engine ignition switch check made? A) Full throttle RPM. B) 1,500 RPM.
|1.||Two igniter plugs.|
|3.||One exciter unit.|
|4.||Two intermediate ignition leads.|
|5.||Two low tension igniter leads.|
How does a gas turbine ignition system work?
Most gas turbine engines are equipped with a high-energy, capacitor-type ignition system and are air cooled by fan airflow. Fan air is ducted to the exciter box, and then flows around the igniter lead and surrounds the igniter before flowing back into the nacelle area.
