Quick question - is the lift generated by coaxial contrarotating blades equal to the lift generated by each individual lifting surface (simplified to lift x 2), or is there a more comprehensive formula available?(adsbygoogle = window.adsbygoogle || []).push({});

Currently, I am using the following formula to calculate the lift of a single disc.

Lift = (8.6859/((Horsepower / Area) ^ 0.3107)) * Horsepower

The remainder of my values are Diameter of 8 1/2 feet and 100 HP. Using simplified value to ensure the calculation is correct.
