In the Helicopter Quartet in particular this is manifested spatially, as the physical separation of the players from the audience and among themselves, circling in the sky in four different helicopters, is overcome through the use of audio-visual equipment, so that "only when transmitted via television screens and loudspeakers in the concert ...
Low-flying, high-speed military aircraft produce especially loud aerodynamic noise. The shape of the nose, windshield or canopy of an aircraft affects the sound produced. Much of the noise of a propeller aircraft is of aerodynamic origin due to the flow of air around the blades. The helicopter main and tail rotors also give rise to aerodynamic ...
Stealth helicopters are helicopters that incorporate stealth technology to decrease an enemy's detection ability. [1] There are a diverse range of technologies used to achieve this decreased detectability; these have largely involved the reduction of several different signatures typically generated by a rotorcraft, including those of noise ...

Helicopters are capable of flying with no more than a few feet of clearance below the helicopter's skids or wheels. Fast jets are more constrained and at a typical low-flying speed of 450 knots (830 km/h), 200 feet (61 m) is not unusual and 50 feet (15 m) is possible in relatively flat terrain.
Airwolf is the helicopter from the 1980s American television series of the same name. Its fictional features included stratospheric ceiling, stealth noise signature, a wide range of weapons and supersonic speed. The Airwolf helicopter was a conventional Bell 222 helicopter modified by attaching some film props.
The restricted airspace was set in place because President Joe Biden is in Delaware over the weekend. The fighter aircraft and helicopter responded to a civilian aircraft at 2:25 p.m. Saturday and ...
The distinct and iconic sound of the helicopters was featured prominently in the film's sound design of the soundtrack. [170] UH-1s were prominently featured in Oliver Stone's 1986 film Platoon. [169] The 1990 film Air America, about the CIA's proprietary airline during the war in Southeast Asia, featured the ubiquitous Huey helicopter. [133]
