AI Technical Summary
Technical Problem
Existing pulsejet engines face challenges with outward protrusion of fuel injectors, increasing engine dimensions and complexity, which complicates integration with airframes and enhances drag.
Method used
The fuel injectors are installed along the inlet pipe axis in an axisymmetric fashion, with angled deflector plates inside the combustion chamber to deflect fuel spray towards the centerline, and a circular fuel rail supplies pressurized fuel, ensuring compactness and efficient fuel-air mixing.
Benefits of technology
This arrangement allows for compact fuel supply and injection systems, reducing aerodynamic drag and simplifying integration with airframes while maintaining engine performance.
