    3. Abstract Three piston radial compressor that can be broken down into three separate slider-cranks. Due to the circular arrangement only one piston will be compressing at a time. Due to similarity between all pistons, only one piston will be discussed for simplicity.

    4. Design Criteria Large stroke length for increased air compression Piston is restricted to linear motion Reduced crank arm length for higher RPM operation Bearings and seals must be able to withstand long term high RPM’s

    5. Specifications Crank Arm Length = 20mm Coupler = 80mm Stroke Length = 40mm Piston Size = 40mm diameter x 20mm depth Operational RPM = 1200 rpm

    13. Results and Conclusions Decided upon a short crank length of 20 mm to increase piston velocity. This lead to a shorter stroke length of 40mm for the piston but with a shorter crank, the piston can maintain a higher rpm. Three piston design for efficiency and heat reduction around each piston. High load bearings are required at all pins to withstand the high rpm’s of the crank arm. Seals must be able to take a vast amount of heat during operation.
