That rocket is/isn't going to fly
Space is no longer only accessible to governments. Nevertheless, developers of small satellites, such as universities and small businesses, must depend on the unused space in large rockets to launch them. This consequently means that they have no control over the timing of the launch and that their choice is limited when it comes to the satellite's orbit.
A wealth of information on noise
In aircraft, noise is an unwanted side-effect of propulsion. In sonar, it is a useful tool for conducting accurate depth measurements. But irrespective of whether it involves a disruptive noise or the useful application of sound, it always tells you something about the source and the surrounding environment. As Associate Professor in the Aircraft Noise and Climate Effects (ANCE) group, Mirjam Snellen specialises in techniques for imaging sound and using sound for imaging.
Let's start the clear sky revolution
On the occasion of Henri Werij’s inaugural speech ‘Let’s start the clear sky revolution’ ten portraits of researchers are on show who, each in their own way, work on making aerospace sustainable or who use aerospace disciplines to make the world a better place. As a passionate amateur photographer the photos have all been taken by Henri Werij himself.
Airplane maintenance at the speed of data
While your airplane is on its way to reach your destination, all airplane systems and components are also on their way, very slowly, from a healthy state to one of malfunction.
Fiery romance: a risk-model for sky lanterns
This week it’s Valentine’s Day as well as Chinese New Year. A popular week for flying sky lanterns. How safe are they and how do you make a risk-model for them?
Kevin Cowan: ‘Rote memorization is not thinking’
Space Engineering lecturer Kevin Cowan wants to teach his students the essence of understanding.
As agile as a bird’s wing
New aircraft materials and structures can save fuel and weight. In the Aerospace Structures and Computational Mechanics research group, Dr Roeland De Breuker and his colleagues are developing the technologies, ensuring that they can be incorporated into the design, and testing them in the lab and in flight. “You have to demonstrate the extent of savings in a credible manner so that an aircraft manufacturer wants to move forward with you,” says De Breuker.
