Propeller pitch is the distance the prop moves forward in one rotation if it were moving through a soft solid. This post explains how to calculate propeller pitch and why it is important.
Flapping wings produce lift and thrust in bio-inspired aerial robots, leading to quiet, safe and efficient flight. However, to extend their application scope, these robots must perch and land, a feat widely demonstrated by birds. Despite recent progress,
ARPC5 residue V8 makes a hydrophobic contact with Arp2 F322. The mother filament is bent where it associates with Arp2/3 complex in the ADP branch junction (Fig. 2). Arp2/3 complex binds on the convex side of the bent mother filament. To measure bending, we generalized methods to ...
The water channel will be 2.75” wide so measure 1 and 5/8” inches left and right of the center point on the flat bottom of the rib profile to allow for the water channel stringer. Make these marks ¼” high. At the outer edge of the flat spot measure ½” up and draw a dia...
The condition of your sales pipeline says a lot about your business. It reveals how close your sales reps are to meeting their quotas, how much revenue you can expect over the next quarter, and whether you have enough new leads to sustain your level of s
Before your sales team can deliver a winning pitch that lands a new customer, they need to know who they should be pitching to. If a lead is passed on to sales before they’re serious about making a purchase, the conversation isn’t likely to end well. S
It has long been recognized that a shallowly submerged submarine traveling beneath the free surface experiences a larger resistance force in conjunction with a lift force and a pitch moment, which all vary periodically with respect to Froude number. As is well known, the periodic behavior of the...
View the world mechanically is a scientific mindset which is also applied to mind in this book. The interests of genes and humans are not the same in general. Genes have a simple purpose of making as many copies of themselves as possible. Humans have much more to desire. Take sex as an...
Fun Fact: FPV drones can’t fly in space because there’s no air for the propellers to move. Understanding Propeller Specifications FPV drone propellers are typically defined by three main dimensions: size, pitch, and blade count. These are often written as a set of numbers, such as 5x4x3...
Measure and cut motor wires, it’s always better to leave a little slack. Strip about 2mm off the tip of the wires and tin the ends. Tin all the motor pads on the 4in1 ESC (fill the pads with a nice dome of solder first before soldering the wires). ...
