1.	Consider the following statements: 1. A Ramjet is a form of an air-breathing using the engine’s forward motion to compress incoming air, without a rotary compressor. 2. Ramjets cannot move an aircraft from standstill. 3. A subsonic combustion Ramjet or Scramjet is a variant of a Ramjet air-breathing. (a) 1 and 2 only (b) 2 and 3 only (c) All of the above (d) None of these
Answer» The correct option is:(a) 1 and 2 only Explanation: ‘Ramjet’ is also referred to as a flying ‘stovepipe’ or an athodyd. Ramjets are frequently confused with pulsejets, which use intermittent combustion but Ramjets employ a continuous combustion process. They can not produce thrust at zero airspeeds. They are also confused with ‘Scramjets’, which are a similar system designed for higher speeds, using supersonic flow.
