DEFINITION

Classification: 60/225

(under subclass 224) Apparatus wherein one of the apparatuses is started after another one of the apparatuses.

(1) Note. This definition includes devices wherein one apparatus is a ram jet which is considered inoperable (i.e., incapable of producing thrust) when static, and therefore may be started only after having been given motion by another motor. These devices may be arranged serially (e.g., rocket and ram jet) having distinctive motive fluid ejecting means for each. The motive fluid ejecting means may be in the form of concentric nozzles arranged so that one may be detached from the other when one motive fluid producing means, e.g., for the rocket, is terminated to provide a new nozzle configuration for the ejection of the motive fluid from the next motive fluid producing means to be activated.
