New Bose technology designed to dampen the road vibration translated into semi-truck cab seats could be applied to helicopters, according to at least one leading aircraft seating engineer.
Earlier this year, Bose unveiled its Ride System for long-haul trucks. The company said the three-part system is the culmination of 25 years of research. It features a suspension base and an integrated, custom-designed seat top. Vibration is mitigated via a high-power, linear electromagnetic actuator capable of counteracting road forces. A compact, bidirectional power amplifier delivers 3,500 Watts to the actuator but draws less power than a 50-Watt light bulb. Sensors and proprietary control algorithms are used to counteract road forces before they reach the driver. Bose tested the system on 77 drivers over the course of a month and 84 percent reported improved comfort, while 66 percent said they were less fatigued. Bose said the estimated cost of the system is “well under $10,000” per unit.
