• Parametric optimization of a flexure-based active Gurney flap mechanism for minimum stress 

  Freire Gómez, J.; Booker, J.D.; Mellor, P.H. (2015)

  The EU's Green Rotorcraft programme is pursuing the development of a functional and airworthy Active Gurney Flap (AGF) for a full-scale helicopter rotor blade. Interest in the development of this ‘smart adaptive rotor ...
• Analysis of high-fidelity reduced-order linearized time-invariant helicopter models for integrated flight and on-blade control applications 

  Padthe, A.K.; Friedmann, P.P.; Lopez, M.; Prasad, J.V.R. (2015)

  Linearized time-periodic models are extracted from a high fidelity comprehensive nonlinear helicopter model at a low-speed descending flight as well as a cruise condition. A Fourier expansion based model reduction method ...
• Value-driven rotorcraft design through integrated product/process development and robust design simulation 

  Schrage, D.P. (2015)

  In his 1999 AHS Nikolsky Lecture: Technology for Rotorcraft Affordability through Integrated Product/Process Development (IPPD)[1] the author described the cultural change taking place in industry and government due to the ...
• Flight simulation of a swashplateless helicopter using rotor RPM variation and movable CG 

  Krishnamurthi, J.; Gandhi, F. (2015)

  This paper focuses on swashplateless primary control of a helicopter using rotor RPM variation in lieu of rotor collective pitch, and longitudinal and lateral cg motion in lieu of rotor cyclic pitch. Using a model of a ...
• Coping with flap and actuator driving constraints in active rotor applications for vibration reduction 

  Morales, R.M.; Turner, M.C. (2015)

  Among the various approaches to mitigate vibration, On-Blade Control (OBC) embeds actuation mechanisms on the blade in order to modify the vibratory loads at the source and achieve improved vibration reduction than ...
