gas turbine combustion chamber

#3. Of the total airflow entering the combustion chamber the percentage that is mixed with the fuel and burnt is:

• A10%
• B40%
• C20%
• D60%

#1. The ratio of air to kerosene to give the greatest heat release during combustion is:

• A45 : 1.
• B130 : 1.
• C12.5 : 1.
• D15 : 1.

#2. One advantage of an annular combustion chamber system is that:

• AThe diameter of the engine is reduced.
• BThere is unrestricted airflow at maximum r.p.m.
• CThere are no flame propagation problems.
• DThe air casing area is greater.
