Statement I: Annular combustors give the most uniform exit temperature.

Statement II: They are the easiest arrangement to develop and test.

In the light of the above statements, choose the correct answer.

  • A.Both Statement I and Statement II are incorrect
  • B.Statement I is incorrect but Statement II is correct
  • C.Statement I is correct but Statement II is incorrect
  • D.Both Statement I and Statement II are correct

Answer: C

The first is correct and the second reverses the truth. Development requires testing the whole annulus, which is expensive compared with rigging a single can, and that ease of development is precisely what kept can and cannular chambers in use for so long.
