Optimal Propeller Calculator where the above calculations are "achieved from the opposite way. Your motor will have a limit to the number of amps it can handle. Lift = C_L * 1/2 * rho* V^2 * Area, so if you increase Vel, V, you increase Lift according to V^2, yet if you make the blade slimmer, you only decrease lift proportional to the reduction of Area. ], Gabriel Staples, "The Goal of a Lifetime," 25 Feb. 2014. We tested it at sea level and about 70F. at or below 700 feet per second or 475 mph. Perhaps you want to know what prop is best? If nothing is amiss, contact Competition Aircraft for engineering assistance. do u have an email that can be contacted? // ger verkningsgraden tipspeed/ spedd of sound engine power AND the perimeter speed is not faster than 230 m/s AND gives This will give you a very shallow negative slope on your dynamic thrust plot (see Figure 2), drastically reducing your static thrust, but dramatically improving your high-speed dynamic thrust. The rest of the graphic is not a real situation on cruise speed. I suspect a Fairley linear curve, and I suspect that a prop in a wind tunnel would draw very little power in a wind nearly it'spitch speed for the given rpm. However, at a fixed RPM, the thrust is certainly linearly dependent on forward airspeed. : 56 in. I'm very new to this whole designing a model thing, and could use an experienced mentor when dealing with stuff like this. …(continued from previous comment)Now, as you stated, you have 2 points, where one is the static thrust (x = 0 and y = static thrust) and one is the zero-thrust airspeed (x = zero-thrust airspeed = pitch speed, and y = 0). Your motor will have a limit to the number of amps it can handle. Anyway, I guess it's not so easy to know Vo, which is relative speed between air and plane. It calculates the theoretical maximum speed of your propeller, based on the prop pitch. In this case INCREASE THE INPUT VOLTAGE to get it back up to 300W input power. Someday I'd like to put some more research and work into it, as I have some more things to learn about propellers and thrust still myself. I remember my delight on that first flight with the new propeller… how smooth it was, and much more noticeable thrust! Also, the distribution of tangential velocity increases linearly with the increase of diameter (again, V = 2*pi*r*n [distance/minute]), but the distribution of lift (Thrust) and drag increase with the square of tangential velocity (again, L = C_L*1/2*rho*V^2), which indicated to me a *probable* change of efficiency (again, I was guessing here) since you're changing RPMs while maintaining a fixed thrust. in extreme situations like acrobatic flying.)
