A modular propeller is a forged propellerusing complex composite materials that has replaceable parts. Parts The purpose of a modular propeller is to provide more user control on boat rally speed. Each modular propeller made of composite materials has three main parts: the hub part with a front-end cap, a set of replaceable blades, and a rear joint to the shaft. The propeller blade parts assembly into slides of the hubrequires not professional assistance, but desscrewing a high quality bronze to remove cone. The blade` bottom joint part of composite blades must be compatible by manufacturer design to overall license the blade assembly for use . In-use performance Modular propellers offer boaters several advantages a fixed-pitch propeller. The ability to change blades allows boat to make adjustments in pitch for various performance needs or a change in altitude. Carrying spare blades for this purpose takes up considerably less space then carrying a complete spare propeller . The ability to replace blades also offers the advantage of replacing damaged blades while still on the water, and saves long term repair costs. Other options include adjusting pitch for altitude, water sports, cruising, and quick turnover time. A virtualisation to render the blade pitch yawing is through car gears. Through an integer yaw pitch of 0-13 degree operating is same: low speed, and more power and acceleration by up gearing the leaver slide.The upper gear of normal cars is comparing to a propeller with a pitch angle of 17+. Good acceleration and top end speed is offered at 21 pitch. A pitch higher than 21 is dangerous because lowering shaft of gearbox back to #1 position stalls engine and blades may crack due to water pressure (read lugging of engine here). The best estimate is that for every 2-inch pitch increase equal wide-opens thrust increase step of approximately 400 RPM. An increase in pitch will cause the rpm-gauge to drop, and an increase in pitch will raise RPM. When changing the prop's pitch it is important to read pictures for range of diameter propeller to engine pin and check slide conformity of blades ` rotor to engine is matching. The plastic shaft joint is supporting the blade set and further on it fits the boat by manufacturer engine URL%DIFDELCMD < %DIFDELCMD < %%% Patent Stahl , B. patent 2006 Category:Propellers Category:Water  transpor
 Unlike a standard one-piece boat or aircraft propeller, a modular propeller is made up of using a number of replaceable parts, typically: a set of matched blades; a propeller hub; and an end cap to retain the blades and to secure the propeller as a solid unit . Ground-adjustable Arplast modular propeller on ARV Super2 Modular propellers may be fitted to aircraft as well as boats.Such as the aviation Arplast Helice ground-adjustable propeller. The benefits of a modular propeller are that its specifications (such as blade pitch or propeller diameter) may be altered to suit varying conditions; and it becomes much easier to replace damaged elements, such as a broken blade. Traditional one-piece propellers may be professionally modified to change the blade pitch , but this is not a common or easy option. In contrast, a modular propeller allows changes to be made quickly and easily.Engineering News - URL %DIFDELCMD < %DIFDELCMD < %%% A modular propeller may have, for instance, a metal hub but composite blades.
