Just the hand launch and thermal currents of rising air ( thermals ) are used to sustain the flight.
2.
Cook tried damping spurious modes by filling the delicate instrument with alcohol, but this induced more instabilities, possibly from thermal currents.
3.
They are designed to be inherently stable in flight; if disturbed by a gust of wind or a thermal current they will return automatically to stable flight.
4.
"They were stuck in Turkey because of the low pressure, when there weren't any thermal currents but now a high pressure ( system ) has brought them south,"
5.
The idea was the diode would rectify the Johnson noise thermal current flucuations produced by the resistor, generating a direct current which could be used to perform work.
6.
Then they will fly prescribed routes, riding on the fuel of rising, boiling thermal currents baked up by the sun as it hits the Eastern Washington plains below them.
7.
"When you get 20 to 30 mph thermal currents and combine that with the big wingspans the birds have, you can see how they've been clocked flying at 60 mph,"
8.
During the intense heat of the middle part of the day, it often soars high in the air, circling up on the thermal currents that rise from the ground below.
9.
The primary passive processes that control the electron and ion collection on an EDT system are thermal current collection, ion ram collection affects, electron photoemission, and possibly secondary electron and ion emission.
10.
And on the personal anecdote side of things, I used to have two dogs that would run around and around out in a big field watching the birds in the sky ride the thermal currents.
