The difference between the geometric pitch and the effective pitch is the angle of attack. It can also be termed as “slippage,” meaning lost work.The actual distance a propeller moves forward through the air in one revolution. It is the difference between the geometric pitch of a propeller...

The transverse circular pitch, pt, is measured along the pitch circle, and the normal circular pitch, pn, is measured normal to the helix of the gear. For a helical gear, the normal and transverse circular pitch are given by Eqns (9.9) and (9.10), respectively, (9.9) (9.10) The ...
Pitch is the perceptual attribute that allows us to order sounds from low to high (ANSI, 1994; low/high refers to the ‘height’ of the sound). Since the note names along the musical scale repeat once per octave, the perception of pitch is commonly represented by a helix with a circular...
2(d). On the other hand, for a left-handed Bouligand structure it is known that in a band of selective Bragg reflection, the wave vector component \({K}_{||}^{{\rm{LH}}}\) parallel to the helix axis of the selectively reflected left-handed mode becomes complex-valued and its ...
The elusive definition of craft beer is not exactly the meaning of life, but you’d think it was given all the attention it gets in craft beer forums (definition: an online symposium of slightly to highly intoxicated enthusiasts of commodified tastes). Guys with chat names like DuffMan23 and...
The distance between two corresponding points on a helix. Pitch The distance that a propeller would travel in an ideal medium during one complete revolution, measured parallel to the shaft of the propeller. Pitch A line of talk designed to persuade "[his] pious pitch for ... austerity" (Bos...
A single book of a publication issued in multi-book format, such as an encyclopedia. The letter "G" was found in volume 4. Pitch Pave (a road) with stones Another sort of stone is used for pitching streets Volume A great amount (of meaning) about something. Pitch (in brewing) add ye...
But within the meaning of this Invention the design of a propeller might be so revised that at a straight-line relationship between the radius of the centrifugal weight and the pitch angle of the propeller blade the centrifugal force just balances the torque. But I also realize, that it is ...
