Abstract
The nozzle-throat insert of an engine is the most important part of the nozzle. In high-performance engines, the nozzle-throat insert cannot only resist high-speed and high-temperature (up to 3,000 K) gas with metal particles, but also produce extremely high-temperature gradient and thermal stress. In order to ensure pressure of the combustion chamber to guarantee the performance of engines, it is necessary to strictly control the ablation of the nozzle-throat insert. This chapter discusses the throat erosion of the fluidic-throat nozzle, and proposes an active thermal protection technology and the throat lining surface compensation technology based on the fluidic throat.
