- However, it is usually a minor gain compared to the airframe's detrimental effect on propeller efficiency.
- The MIDP increased propeller efficiency and virtually eliminated the shipyard downtime which was formerly necessary for repairing the erosion problems.
- The extra factor of / ?, with ? the propeller efficiency, in the second equation enters because = ( required thrust ) ?/ ?.
- There have been propeller aircraft which attained up to the Mach 0.8 range, but the low propeller efficiency at this speed makes such applications rare.
- Turboprops generally have better performance than turbojets or turbofans at low speeds where propeller efficiency is high, but become increasingly noisy and inefficient at high speeds.
- The outer engines remained unchanged, but were moved from their original position to mountings on faired struts midway in the interplane gap, to improve propeller efficiency.
- Curve for the light aircraft with the drag polar above and weighing 2000 kg, with a wing area of 15 m?and a propeller efficiency of 0.8.
- Remarkably, German wind-tunnel tests showed that the simple rounded nose improved propeller efficiency and raised the top speed by 14 km / h ( 9 mph ).
- However, there is a tradeoff in propeller efficiency compared to forward speed, so while the turboprops are efficient engines, they are only efficient at speeds of up to.
- The forces associated with air moving around the tiny devices are more pronounced than with conventional aircraft in flight, causing increased drag, reduced lift under the smaller wings at low speeds and decreased propeller efficiency, engineers say.
- The advantages of the engine were increased propeller efficiency through the reduction gearing effect of having the engine effectively running at 1, 800 rpm for only 900 rpm of the airscrew, and excellent high-altitude performance due to the high compression ratio achieved.
- Even before the start of World War II, engineers were beginning to realize that engines driving propellers were self-limiting in terms of the maximum performance which could be attained; the limit was due to issues related to propeller efficiency, which declined as blade tips approached the speed of sound.
- If the reduction in pressure is too much in relation to the ambient pressure of the fluid, " cavitation " occurs, bubbles form in the low pressure area and are moved towards the blade's trailing edge where they collapse as the pressure increases, this reduces propeller efficiency and increases noise.
- The Bureau of Aeronautics analyzed the possibilities of the plane becoming a competitive race plane, and decided that the extra weight of the supercharger could be better put to use by installing an epicyclic reduction gear, for improved propeller efficiency, thereby providing greater improvement in performance than what the supercharged engine with a direct drive propeller could provide for the same weight.
