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

Temperature Measurements

Air Density v. Temperature

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.
