Blade Element Theory Prof. Dr. Mustafa Cavcar Anadolu University‚ School of Civil Aviation Eskisehir‚ Turkey mcavcar@anadolu.edu.tr The simple momentum theory provides an initial idea regarding the performance of a propeller but not sufficient information for the detailed design. Detailed information can be obtained through analysis of the forces acting on a blade element like it is a wing section. The forces acting on a small section of the blade are determined and then integrated over

AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up. Built around only one NAND gate IC (CD4011)‚ the circuit is simple‚ compact and economical. It works off a 12V DC power supply and consumes very little power. The circuit can be divided into two parts: controller circuit and

ANALYSIS The vane shear apparatus makes use of the theory that the summation of the total shear stress is equal to the sum of the shear stress at failure along the cylindrical surface and the total shear stress on the top and the bottom of the surface of the cylinder. The various sizes of the vanes are accounted for by applying the multiplying factor. The value obtained from the medium sized vane is the value of the stress itself‚ and there is no need to multiply or divide the value. The values
