These included a 2-cylinder water-cooled 27 hp MHI model KE130 diesel engine, a creeper gear that reduced first speed ground speed to 0.20 mph, a rear and a mid 540 or 1-000rpm PTO, and a direct-drive engine speed pulley with electric clutch for a mid-mounted 60-inch rotary mower.
After the Flt08A release at 1001:00 UTC, the WTE gained about 37 m in altitude traveling into the wind, and with a relative [Wind.sub.Bk] of 15ms 1 and a ground speed of 5 m [s.sup.-1], few wingbeats were undertaken.
"The drone's top speed is actually 179.6 miles per hour, but in order to be officially recognized by the Guinness World Records for the fastest ground speed achieved by a battery-powered remote-controlledquadcopter, the DRL Racer X had to fly back and forth across a 328-foot long course, with the top speeds of both runs averaged together.
First, image spatial resolution depends on the resolution of the camera detector, the field of view (FOV) provided by the lens, the camera exposure time, and the altitude and ground speed of the aircraft.
(5,694.4 Nm) of rotational torque--along with improved ground speed, carriage speed, rotational speed and rod breakout efficiency --the D24x40 S3 is built to help maximize machine and jobsite productivity.
While other low-cost A FIRS for light aircraft rely upon GPS ground speed as a corrector, we chose pitot rather than a CPS to allow our system to be installed without requiring a GPS input.

Ground speed has been increased and a new steering geometry means that negotiating trees in an orchard or cutting around flower borders is fast and effortless work.
If the available power was marginal to begin with, a rotor "droop," and potential LTE/LTA are likely, as the attempt is made to decelerate to zero ground speed, with tail-to-the-wind.
A report by the Air Accident Investigation Branch revealed that the nose wheels and tyres were damaged after the "aircraft left the paved surface of the taxiway and came to rest on grass beside it, having turned to vacate the runway at approximately 20 kt ground speed."
