(Nederlands) Mark van Venrooij nieuwe NLR divisiemanager Aerospace Systems

Mark van Venrooij (1965) is per 1 september 2016 benoemd tot divisiemanager Aerospace Systems van het NLR. Hij treedt daarmee toe tot het Directieteam van het NLR. Mark volgt Eddy Pijpers op, die na meer dan 30 jaar afscheid neemt van het NLR.

Mark van Venrooij heeft Lucht- en Ruimtevaarttechniek gestudeerd aan de TU-Delft en werkt sinds 1991 bij het NLR. Zijn eerste functie bij het NLR was de operationele analyse van Luchtmacht oefeningen en operaties. Vervolgens werd hij benoemd tot programmaleider van diverse onderzoeksprogramma’s en sinds 2007 was hij hoofd van de afdeling Defence Operations.

Mark van Venrooij heeft gedegen kennis van de sector en ruime ervaring met toegepast onderzoek op het gebied van lucht- en ruimtevaart, ten behoeve van bedrijfsleven en overheid, in het bijzonder voor Defensie. Mark hecht veel waarde aan intensieve samenwerking tussen bedrijfsleven, overheid en kennisorganisaties als het NLR. “Het NLR streeft er voortdurend naar om zijn integrale systeemkennis en hoogwaardige technologieën in te zetten voor innovatie bij Defensie en industrie. Integratie van nieuwe technologieën zijn voor onze klanten cruciaal”.

Mark van Venrooij heeft een partner en is vader van 2 zonen.

De Aerospace Systems divisie van het NLR bestaat uit de afdelingen Aerospace Electronics & Qualification, Flight Test & Certification, Defence Operations en ISR & Space Utilisation.

Maple seeds determine optimal flight route for unmanned helicopter

Esdoorn vluchtHow can an unmanned helicopter land safely even after its engine fails? The answer can be found in flights of maple tree seeds, as researched by NLR’s Skander Taamallah.

The seeds of the maple tree – nicknamed ‘little helicopters’ – are constructed in such a way that as they fall they create lift and hence fall slowly towards the ground. These flight conditions (i.e. auto-rotation) ensure that the wind can spread the seeds far and wide. “When the maple leafs fall, they turn like a helicopter in auto-rotation. Consequently, I used this – Mother Nature’s seed spreading concept – during my PhD research to allow for safe landings of unmanned helicopters,” Skander Taamallah says.

Auto-rotation is the effect that occurs when the engine of a helicopter stops working, whereby the main rotor and tail rotor are still able to rotate freely. If a helicopter has enough height and/or speed, the rotors will keep turning, thus allowing the helicopter to enter a gliding flight and land safely.

Skander Taamallah began by modelling the dynamics of a small-scale helicopter, which he then studied in a simulated helicopter environment. His next step was to calculate the optimal flight path of the unmanned helicopter whose engine had failed. To establish its optimal flight profile, he established the speeds at which the unmanned helicopter would be travelling for all altitudes, from the start of the descent to landing. Skander Taamallah concluded his PhD research by developing a control algorithm, which ensured that the helicopter would remain flying as close as possible to the optimal flight path during the entire descent.

Skander Taamallah however still faces a key challenge: in order to validate his simulations, he intends to use a small-scale, unmanned helicopter to test the automated auto-rotation during a real flight. We eagerly look forward to it!

Skander Taamallah received his PhD from TU Delft on September 18th 2015. You can download his dissertation Phd book.

Michel Peters named Vice-Chairman of IFAR


Global solutions for major aviation questions

Michel Peters, CEO of the Netherlands Aerospace Centre (NLR), was appointed Vice-Chairman of IFAR, the International Forum for Aviation Research. Peters was appointed at IFAR’s 6th annual meeting, held at NASA’s Ames Research Center, in California, USA.

IFAR is comprised of 26 global aviation and aerospace research organisations that collaborate in order to jointly address the challenges facing the global aviation sector, such as technological issues that transcend national borders, including emissions, noise disturbance, safety, security and efficient operations.
In the presence of representatives of 21 aviation research organizations, the global leaders in aviation evaluate the progress of technological collaboration pertaining to aviation’s impact on the environment. Examples of this include research into alternative fuels, the development of a comprehensive approach to ATM research, the supersonic aircraft, and wind tunnel tests.

IFAR’s focus is on global issues, which are further subdivided into working groups. Consequently, NASA, for example, leads the ‘Air Transport Efficiency’ and alternative fuels working group. NLR meanwhile leads the ‘Impact of Weather on ATM’ working group. For the NLR, this means that we collaborate with dozens of other organisations to initially identify existing research activities that are globally relevant for this subject and render it possible to exchange associated information.

In addition to promoting scientific and technical expertise, IFAR promotes exchanges of young researchers. Hence, during IFAR’s recent meeting, a Young Researchers conference was held, during which IFAR participants from various countries exchanged ideas pertaining to the future of aviation. For networking purposes, researchers can benefit from the shared use of www.ifarlink.aero (for IFAR members and researchers at universities, related to aviation and aerospace)

The NLR follows DLR, NASA and JAXA in assuming the Vice-Chairmanship. The NLR is regarded and renowned as a leading organization in the field of aviation. Michel Peters will assume the chairmanship of IFAR in two years. Peters: “IFAR is an important global networking platform for both CEOs and scientists. IFAR’s focal point is the future of aviation. As the NLR, we must be a part of this platform. NLR is already participating in various working groups, such as ‘weather’ and’ air traffic management’. We do this on a modest scale, as there is no allocated funding available, but we engage in areas of interest.”

The next IFAR meeting will be held in the autumn of 2016 at the Korea Aerospace Research Institute, in Daejeon, South Korea.
