Abstract
A system for measuring supersonic nozzle exhaust flow, comprising a seeding module, an optics module configured to direct an optical signal from the supersonic nozzle, and a streak camera. The streak camera is optically connected to the optical signal, the streak camera configured to image the path of the seed particles traveling in the nozzle exhaust flow. The seeding module includes a seed particle container and a seed particle injector configured to inject seed particles into a supersonic nozzle flow. The streak camera comprises a photocathode, a sweep module, a micro-channel plate, a phosphor screen, and a charged coupled imaging device.
