1/3 What a gorgeous mild summer day. Hung out at the pier at 44th street, lucky to see big boat action.

Yesterday gliders, today we step up: some beautiful propeller-driven trainer aircraft, from classics to modern! ✈️

Kleine Geschenke sind oft die schönsten. Den #Propeller hätte ich beinahe verloren, den aber dann richtig festgezogen ... !!!

Ich liebe sie 🥰❤

Successful high power test of the glider's electric motor with the spinner and propeller installed.

I had it at full power: 4600 RPM and 150 amps at 115 volts DC. I conducted this test three times. No problems with vibrations, excessive temperature of the motor or any other components, or rapid draining of the batteries.

This is a major milestone for the electric motor system.

Quietening Drones

A drone’s noisiness is one of its major downfalls. Standard drones are obnoxiously loud and disruptive for both humans and animals, one reason that they’re not allowed in many places. This flow visualization, courtesy of the Slow Mo Guys, helps show why. The image above shows a standard off-the-shelf drone rotor. As each blade passes through the smoke, it sheds a wingtip vortex. (Note that these vortices are constantly coming off the blade, but we only see them where they intersect with the smoke.) As the blades go by, a constant stream of regularly-spaced vortices marches downstream of the rotor. This regular spacing creates the dominant acoustic frequency that we hear from the drone.

To counter that, the company Wing uses a rotor with blades of different lengths (bottom image). This staggers the location of the shed vortices and causes some later vortices to spin up with their downstream neighbor. These interactions break up that regular spacing that generates the drone’s dominant acoustic frequency. Overall, that makes the drone sound quieter, likely without a large impact to the amount of lift it creates. (Image credit: The Slow Mo Guys)

Woooh!
100 year old trade barriers finally coming down.
Not just pulling US alcohol off the shelf, replacing it with Canadian!

I'm shipping my family in #BC some #Quebec sour beer while its still exotic.
Personally I'm looking forward to grabbing some #Driftwood from #BC and #Propeller from #NovaScotia.

#MAGA #propeller

It looks like #donaldtrump has grown an extra pair of arms to speed up the making of #america great although the use of 'again' is very disputable! I cannot think of a period when America was great except for in the time before #columbus arrived to the new world to bring annihilation, disease and... a religion with a man nailed on a cross!
