Abstract Expander bleed cycles have a rather simple configuration when compared to other engine cycles, making them appealing when a new low-thrust engine must be designed. This type of cycles can only operate with light fuels that can be pumped in the liquid state and then properly expanded as a gas in the turbines. As a consequence of the limited amount of power provided by the coolant, expander cycles are characterized by a maximum thrust level of a few hundreds of kilonewtons. The present study focuses on the analysis of a liquid oxygen/liquid hydrogen expander bleed engine cycle dedicated to upper stage applications. A basic selection of all the key parameters defining the engine and its subsystems is carried out to obtain a specific configuration able to work at a prescribed working point. Starting from this configuration, a parametric analyses is performed to study the effect of single component properties and modelling on the expected overall engine performance.
