Final answer:
The interconnecting tubes between can-type combustion chambers in a jet engine ensure flame stabilization by allowing a flame to propagate from one chamber to another in case of a flameout, thereby preventing engine failure.
Step-by-step explanation:
The interconnecting tubes attached between can-type combustion chambers in a jet engine play a crucial role in ensuring consistent operation across all chambers. These tubes primarily serve the purpose of flame stabilization.
In a jet engine, if one combustion chamber were to extinguish or fail to ignite, these interconnecting tubes allow the flame from an adjacent functioning chamber to re-ignite the fuel-air mixture, thus maintaining continuous combustion. It is a safety feature that helps prevent flameouts that could lead to engine failure. Therefore, the correct answer to the purpose of the interconnecting tubes is (b) Flame stabilization.
