Coaxial rotor helicopters have a wide range of civilian and military applications; however, the collision risk upper lower blades that comes with coaxial system remains. This paper introduces blade-tip distance measurement method based on coded ultrasonic ranging to tackle this challenge. Coded phase modulation was adopted improve rate. In paper, seven-bit M-sequences Gold codes are chosen four periods 200 kHz sine wave carriers as excitation signals, received signals filtered by bandpass...
Coaxial rotor helicopters have great potential in civilian and commercial uses, with many advantages, but challenges remain the accurate measurement of blades’ distance to prevent blade collision. In this paper, a tip method based on ultrasonic window phase triggering is proposed, time transmitter studied. Due complexity measured signal, bandpass filtering time-of-flight (TOF) estimation power density received signal are utilised. The tested an experimental test platform pair 200 kHz...
Postmodernist writer Donald Barthelme in his work “Snow White” reimagines the archetypal characters from Brothers Grimm fairy tales as disenchanted anti-heroic figures. His multiple rewrites of identities such princess, dwarfs, and prince not only reflect de-authoritative characteristic postmodern literature, but also mirror map assemblage consisting molar lines, molecular lines flight proposed by contemporary French postmodernist philosophers Gilles Deleuze Félix Guattari, through which...
Coaxial rotor helicopters have many advantages and a wide range of civilian military applications; however, there is risk blade collision between the upper lower blades, challenge still exists in balancing parameters flight control. In this paper, tip distance measurement method based on coded ultrasonic ranging phase triggering proposed to tackle environment expand application high-speed dynamic measurement. The time (Tof) calculated by amplitude threshold improvement cross-correlation...
With the advancement in automatic driving technology, testing methods-such as road test for conventional is difficult to verify safety and reliability of vehicles. Virtual method has become an important mean due technical superiority efficiency time consumption. This paper selects a highway traffic accident from China In-Depth Accident Study (CIDAS) database analyzes cause. Builds scenario virtual simulation software-CarMaker, including actual environment information, ego vehicle, other...
