A recor has a rectangular blade planformi, a solidity of 0.1, ideal blade twist, and operates in hover at a thrust coefficient of 0.008. By numerical means, using the combined blade- clement momentum theory (BEMT), compare the predicted inflow ratio acmiss the span of the blade with the exact (analytic) resalt. Show also the radial distributions of thrust, induced torque, and lift coefficient, and compare with the solutions obtained using the exact theory. Finally, compare the numerical calculations of the integrated thrust and induced power with the exact results for this rotor over the range 0.00 0.010.
