Pagination or Media Count:
A rate-of-fire recorder has been developed, employing a galvanometer oscillograph with contacts on each gun. It is used for recording individual cyclic rates-of-fire of several guns firing simultaneously, referred to a common time scale on the same record. The recorder is fully automatic in operation, quickly changed from one aircraft to another by virtue of its external stowage, and is easily accessible for service. Construction details are described.
