Altena, A. (author), Luesutthiviboon, S. (author), de Croon, G.C.H.E. (author), Snellen, M. (author), Voskuijl, M. (author)Due to technological advances in the drone industry, security threats induced by unmanned aerial vehicles (UAVs) are becoming more relevant. Fast and accurate localisation systems need to be designed. One approach is localisation of UAVs by their sound using acoustic techniques. So far, a systematic performance assessment of acoustic...conference paper 2023

Zahoor, Y. (author), Sodja, J. (author), De Breuker, R. (author), Voskuijl, M. (author)This paper discusses the development and whirl tower testing of an active translation induced camber morphing system for rotorcraft. The system deploys the morphing flap based on the amplitude and type of the input signal. As a case study, a demonstrator is developed and tested primarily under the centrifugal force generated by a whirl tower...conference paper 2021

Varriale, Carmine (author), Voskuijl, M. (author)This paper presents a Control Allocation formulation aimed at altering the dynamic transient response of an aircraft by exclusive means of the aerodynamic effectiveness of its control effectors. This is done, for a given Flight Control System architecture and, optionally, closed-loop performance, by exploiting the concept of Control Center of...journal article 2021

Varriale, Carmine (author), Voskuijl, M. (author)This paper presents a generic trim problem formulation, in the form of a constrained optimization problem, which employs forces and moments due to the aircraft control surfaces as decision variables. The geometry of the Attainable Moment Set (AMS), i.e. the set of all control forces and moments attainable by the control surfaces, is used to...journal article 2021

Soares Pinto Leite, J.P. (author), Voskuijl, M. (author)Purpose: In recent years, increased awareness on global warming effects led to a renewed interest in all kinds of green technologies. Among them, some attention has been devoted to hybrid-electric aircraft – aircraft where the propulsion system contains power systems driven by electricity and power systems driven by hydrocarbon-based fuel....journal article 2020

Duivenvoorden, R.R. (author), Voskuijl, M. (author), Morée, Lars (author), de Vries, J. (author), van der Veen, Finbar (author)The use of formation flight to achieve aerodynamic benefit applied to rotorcraft has, unlike its fixed-wing counterpart, received little attention in the literature. This document presents a proof-of-concept of rotorcraft formation flight from two independent investigations: a numerical study of a fully articulated helicopter influenced by an...journal article 2020

Zahoor, Y. (author), De Breuker, R. (author), Voskuijl, M. (author)This paper presents an overview of the preliminary design process and findings aimed at morphing of trailing edge (TE) control surfaces for rotorcraft. A design methodology for a camber morphing control surface is presented, although twist can also be induced by applying differential camber of the morphing section span. The concept investigated...conference paper 2020

Varriale, Carmine (author), Veldhuis, L.L.M. (author), Voskuijl, M. (author)This paper presents a method to find trimmed flight conditions while maximizing the available control authority about one or more motion axes. Maximum pitch-up, or lift-up, control authority could find interesting application in aborted landing situations, while maximum balanced control authority about all motion axes is a reformulation of the...conference paper 2020

Duivenvoorden, R.R. (author), Voskuijl, M. (author), Morée, Lars (author), de Vries, J. (author), van der Veen, Finbar (author)The use of formation flight to achieve aerodynamic benefit as applied to rotorcraft is, unlike its fixed-wing counterpart, an unproven principle. This document presents a proof-of-concept of rotorcraft formation flight through a numerical research study, supported by results from an independent wind-tunnel experiment. In both cases, two...conference paper 2020

Varriale, Carmine (author), Hameeteman, Kevin (author), Voskuijl, M. (author), Veldhuis, L.L.M. (author)The aim of this research is to investigate the combined use of throttle and aerodynamic control vanes for aircraft optimal control. A new disruptive aircraft configuration concept is presented, featuring control vanes downstream of two rear-mounted ducted propellers. The aerodynamic interaction between the horizontal vane and the throttle is...conference paper 2019

Raju Kulkarni, A. (author), Varriale, Carmine (author), Voskuijl, M. (author), la Rocca, G. (author), Veldhuis, L.L.M. (author)Sub-scale Flight Testing (SFT) is potentially useful in predicting aircraft flight behaviour, especially in the case of unconventional designs for which legacy information is unavailable and wind tunnel tests are unable to predict aircraft dynamics. A necessary condition for SFT is the design of properly scaled models. However, even in case of...conference paper 2019

Voskuijl, M. (author), Muhammad Ridho Said, Muhammad Ridho (author), Pandher, Jaspreet (author), van Tooren, Michel (author), Richards, Blin (author)Several morphing unmanned aircraft systems which can be deployed in-flight are currently being developed for a variety of missions. Key to a successful in-flight deployment of these aircraft is that they enter a stable and controllable flight phase following a potentially highly dynamic transition phase without exceeding structural limitations....conference paper 2019

(author), Eglin, Paul (author)Installation effects of the lateral rotors for a compound helicopter were investigated by means of unsteady CFD simulations. The helicopter featured a box-wing design for additional lift in cruise and wingtip-mounted lateral rotors in pusher configuration for additional thrust in cruise and counter-torque in hover. It was found that propeller...journal article 2018
