Discussion
Consider the following statements about combustor performance:
1. Pressure loss of three to six per cent is typical.
2. Pattern factor governs turbine blade life.
3. Combustion efficiency at cruise clearly separates good chambers from poor ones.
Which of the statements given above is or are correct?
Answer: A
Correct answer: 1 and 2 only
Statements 1 and 2 are correct: three to six per cent pressure loss is typical, and pattern factor governs turbine blade life through the temperature the hottest blade sees. Statement 3 is wrong for the reason the topic returns to repeatedly - every serious design exceeds 99 per cent at cruise, so the parameter discriminates between none of them.
