Rotary Vane Engine Model

I designed and made this educational model of a Rotary Vane Engine. It functions much the same as a Wankel Rotary Engine, however the rotor instead has vanes that retract as it spins. The fundamental function is identical:Air intake: cold air is pulled in (snowflake)Fuel injection: An air-fuel mixture is added to the cold air (droplet)Spark: A spark plug ignites this mixture under great pressure, forcing the vane round (lightning)Exhaust: Hot combusted air is removed from the chamber (flame)One
