Injector Design

What is it about?

An innovative parametric model was developed to the design of certain elements of the liquid propellant thrust chamber, the propellant injector. Considering the level of details and accuracy appropriated to the stage of conceptual analysis or preliminary design. With the goal of defining the geometry required for obtaining the mass flow rate, the work contributes to a new approach as it assigns different values for the discharge coefficient and the outlet openings of the swirl injector. For the Pintle injector that work presents a contribution to the definition of the internal architecture of the device and the respective calculations that can guarantee the expected mass flow.

Why is it important?

A new generation of engine for efficient rockets moves in the scenario demand strongly focused solutions in the cost and benefit ratio to the detriment of the search for performance. Opening possibilities for creation of modern design tools that incorporate the knowledge accumulated in the recent decades and can be combined with modern data processing technologies, reducing the volume of resources needed to achieve the expected results. It was within this context that an innovative parametric model was developed.
