1. Design a small, single-cylinder Stirling or Ericsson cycle external combustion engine that can be used to demonstrate the operation of this type of engine in the classroom. Choose a convenient fuel such as alcohol. Provide detailed working drawings and a thermodynamic analysis.
2. Design a Brayton cycle power system to propel a small drone aircraft that will be used for military target practice. The fueled drone must weigh less than 500. kg, and since these aircraft are not reusable, they must be produced at minimum cost.
Determine or specify the air mass flow rate, pressure ratio, compressor and turbine isentropic efficiencies, turbine inlet temperature, thrust, thrust to weight ratio, exhaust temperature, and hot ASC thermal efficiency. A computer program will help you carry out parametric studies of the variables involved.
