What is a key characteristic of multi-chamber combustion cans in turbojet engines?

• A. Increased airflow resistance
• B. Enhanced thermal stability
• C. Lower weight
• D. Improved fuel efficiency

Answer: (D)

A key characteristic of multi-chamber combustion cans in turbojet engines is their improved fuel efficiency. This design allows for a more uniform distribution of fuel and air within the combustion process. By separating the combustion into multiple chambers, the engine can achieve a more stable and complete combustion reaction. This results in better combustion efficiency, which translates into more efficient fuel usage. The design also helps to manage the combustion temperature more effectively, reducing the likelihood of flameout and improving overall engine performance under various operating conditions. As a result, the enhancement in fuel efficiency contributes to better engine performance and extends operational range and endurance without a corresponding increase in fuel consumption. Other attributes of the multi-chamber design include improved thermal management and reduced weight relative to equivalent single-chamber designs, but the primary benefit lies in the enhancement of fuel efficiency during operation.
