A crash cushion installed on a motorway exit in Italy. An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.
The first track to be started onsite was an initial 6 mi (9.7 km) segment of the planned Linear Induction Motor Research Vehicle (LIMRV) test track, built by Morrison-Knudsen; it was anticipated that the initial segment would later be extended to a full 21.8 mi long (35.1 km) oval and a parallel oval guideway would be completed for the Tracked Air Cushion Research Vehicle (TACRV).
Although in rundown condition, both cars were able to refurbished enough to be crash-tested, and the airbags deployed perfectly in both vehicles. [ 2 ] Due to success of the test fleet, GM decided to offer the ACRS as an option for full-size Cadillacs , Oldsmobiles , and Buicks for the 1974 model year. [ 3 ]
On 29 June 1987, approval was granted for full LCAC production. Forty-eight air-cushion landing craft were authorized and appropriated through FY 89. Lockheed Shipbuilding Company was competitively selected as a second source. The FY 1990 budget request included $219.3 million for nine craft.
The 'classic' one-car crash results when a vehicle slowly drifts to the right, hits dirt or rumble strips on the right shoulder of the road, and the driver becomes alert and overreacts, jerking the wheel left to bring the vehicle back onto the road. This motion causes the left front tire to strike the raised edge of the pavement at a sharp ...
An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...
THOR 50 ATD Child ATD - Q10. Humanetics makes a variety of crash test dummies, ranging from newborn infants and adults to the obese and the elderly. [23] [24] The company works with agencies and industry groups such as NHTSA, Euro NCAP, and the University of Michigan's International Center for Automotive Medicine (ICAM) to design crash test dummies that reflect changing worldwide demographics ...
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.
