The mathematics behind using the Turbo-Prop for lift off and flying .
The key to flying is being able to over come the weight of the pilot as well as the equipment being used during flight . As shown in the Turbo-prop specifications, each turbo-prop has approximately 55 Lbs of thrust .
An average man will weigh about 215 Lbs or 15 stone . To overcome this weight we will be using 6 Turbo-Props with a thrust of 55 Lbs each . So doing the maths you have :
6 Turbo-props multiplied by 55 Lbs of thrust = 330 Lbs of Maximum thrust . Take into consideration that each turbine weighs 4.9 Lbs . 4.9 Lbs multiplied by 6 turbines = 29.4 Lbs of turbine weight . Taking weight into consideration 215 Lbs ( of man weight ) in addition to 29.4 Lbs of Turbo-Prop weight will = 244.4 Lbs of minimum weight . Leave you with 85.6 Lbs of usable lift for take off .
The frame and electrical equipment must all weigh less than 85.6 Lbs . To overcome this probably adding another 1 or 2 Turbo-props would give the required lift for take off .
The required lift for take off will depend on the weight of the frame plus turbines, fuel tank, fuel and onboard flight electronics used which will in turn determine the number of turbo-Props used . Using 6 Turbo-Props will give you 20 minutes of flying time consuming 7 Gallons of Kerosine . The weight of 1 Gallon of Kerosine is 6.82 Lbs based on a cubic foot of Kerosene is 51 Lbs or 7.48 Gallons in a cubic foot .
fuel consumtion for each Turbo-Prop is 8 oz a minute . So using 6 turbo-props would result in a consumption of 48 oz a minute .
