Objectives
• The engine should be easy to start and operate
• The assembly will be lightweight and easy to transport
• The cart tipping force will be sufficiently large to prevent
any possible accidents
• The engine will produce a desired thrust
• Oil temperature must remain under 100˚C
• The system will run for a sufficient time to allow for
thorough testing
Operation
Conceptual Design
Turbocharger
Mitsubishi TD04-12T
• Compresses upstream air
• Turbo shaft is forced to
spin by high energy fluid mixture
Cart Assembly
Combustion Chamber Design
Combustion Chamber Design
Nozzle Design
• Reduction of area from 1.65 to 1.18 inches
Oil System
Oil System
Propane Delivery
• Originally, a ball valve was used for fuel delivery
• The ball valve was replaced with a gate valve, which
provided better control

Velocity Measurements
• 6 inch pipe was used to lower inlet velocity to an acceptable value ( < 30 m/s)
Velocity Measurements
• 𝑉𝑖 =𝑉6∙𝐴6
𝐴𝑖, where V6 is the velocity at the 6 inch inlet and
A6 is the area of the 6 inch inlet
Results
• 𝑇ℎ𝑟𝑢𝑠𝑡 = 𝑚 𝑇 𝑉𝑒 − 𝑉𝑖 , where 𝑚 𝑇 is the total mass is flow rate, 𝑉𝑒 is the nozzle exit velocity, and 𝑉𝑖 is the compressor inlet velocity.
