dc.description.abstract | The term inceptor refers to the controls pilots use to orientate and manoeuvre an aircraft, applicable to both fixed or rotary-wing aircraft. Active inceptors are unique in that they include the ability to provide tactile force feedback from the aircraft control surfaces to the pilot; the pilot is able to experience the aircraft dynamics. Typical active inceptor anatomies comprise components interconnected through a network of mechanical links and understanding how these individual components behave collectively under the influence of helicopter vibratory loads is crucial in assessing the dynamic response of the entire inceptor. This paper presents an investigation into the mathematical modelling of a candidate inceptor mechanism using a dynamic modelling approach formulated by Udwadia-Kalaba to explore resonance frequencies. Results demonstrate the ability of the Udwadia-Kalaba scheme to model and capture the location of the inceptor mechanism’s resonance frequencies. Sensitivity studies were also conducted on selected inceptor design parameters to demonstrate that system resonance frequencies may be influenced and tuned away from baseline values. | |
