The Corvo Precision Payload Delivery System (PPDS) is a small aerial drone originally intended for logistics, weighs 2.4 kg (5.3 lb) empty, and deliveries payloads of up to 3 kilograms (6.6 lb). [1] The airframe is made of waxed foamcore (foamboard) and the drone is supplied as a self-assembly flatpack, complete with a tablet-PC control centre ...
Transmission line loudspeakers employ this tube-like resonant cavity, with the length set between 1/6 and 1/2 the wavelength of the fundamental resonant frequency of the loudspeaker driver being used. The cross-sectional area of the tube is typically comparable to the cross-sectional area of the driver's radiating surface area.
The drone measures around 16 × 2.5 cm (6 × 1 in) and provides troops on the ground with local situational awareness. It is small enough to fit in one hand and weighs 18 g (0.7 oz) with its battery. [5] The UAV is equipped with a camera which transmits video and still images to the operator.
Craig's father, Thomas, sees the drone and accuses Stephen of flying it as he is the only person in South Park with a drone, but Butters manages to fly the drone back before it can be discovered missing. Thomas makes Stephen wonder if the drone is capable of flying itself, as Butters is not allowed to fly it without his father's supervision.

The drone attack was one of dozens on U.S. troops in the Middle East since Hamas launched attacks on Israel on Oct. 7, igniting the war in Gaza. But it’s the first in which American service ...
The parameter "ka", which is the wave number multiplied by the speaker radius, is often used to characterize sound source directivity. For this source, ka=19 at 2.5 kHz, and according to the LRAD data sheet, the beam angle of about 30 degrees total is what is predicted for a regular loudspeaker. [8] [needs update]
