This engine page was gone for some years. I found it again.
This is a half Radial Circular Engine , i think it is stupid , it is a reciprocating Flaps Circular engine ,go figure.
you can see there analisys of the normal Piston engine with the equation
F = P. A . Sin (α+β)
the equation they give for circular engines is adaptable i think to all circular engines.
F = P x A
As you can see they didn’t add the Radius of the (crank,disk) FLAPS their equation , it seems since the engine is small, they consider the attribute of Radius radios is equaling and taken into consideration when calculating the area of the flaps , so there Equation doesnt have any R in it.
while for any other Circular Radial Engine the equation would include the measurement of the Radios Radius in it , since it is after all the Radians of the disk holding the pistons is the length of the Torque arm . so the final Equation for any circular engine i think would be
F=P x A x R
can you see how great the power is just by comparing the two equations?
F = P.A. Sin (α+β)/ Sin (β)
the part (Sin (α+β)/ Sin (β)) is actually is the changing Length of torque arm of the reciprocating Piston engine. and removing it with a steady length (R) makes the engine a HOLE LOT MORE FASTER and POWER FULL.
