Abstract

The subject of this development is a linerless nozzle manufactured by filament winding process with prepreg carbon fiber. The nozzle will be assembled on a hybrid rocket motor planned by Brazilian Space Agency - AEB in the SARA project, to desecelerate a low orbital satellite in the reentry to the atmosphere. The nozzle during ignition time of about 12s is submitted to inner pressure, axial force, erosion and high temperature. The development consists of structural analysis, the lay up definition, the determination of process variables and the manufacturing by filament winding process in which process variables were simulated with specific CAD-CAM software. Due to the bell shaped inner surface of the nozzle, a high slippage tendency occurs during winding and restricted the winding angle alternatives. To withstand high temperature a special coating were developed and applied directly on the mandrel before the winding procedure. Partial tests showed the viability to manufacture the nozzle with prepreg carbon fiber and epoxy matrix by the filament winding process.
