Folding-shearing

50% of all sheet metal is scrapped, mainly by trimming following deep-drawing. To combat this a novel process inspired by the mechanics of spinning is proposed and its feasibility is tested with a novel experimental rig. A...

Novel Approach to Leading-Edge Vortex Suppression
A novel approach to reduce the peak lift and pitching moment on a plunging airfoil is investigated through force, moment, and velocity measurements. This approach, unlike previous investigations of delayed flow separation and...

Thrust enhancement due to flexible trailing-edge of plunging foils
Drag reduction for hydrofoils is studied through thrust generation on foils plunging at low Strouhal numbers in order to simulate the action of the ocean waves. Force, deformation and flow field measurements are presented for a...

Lift reduction by counter flowing wall jets

Counter flowing wall jets are proposed to reduce extreme loads, enabling lighter and more efficient aircraft. Upstream blowing on the upper surface of a NACA0012 airfoil at a Reynolds number of 660,000 was investigated by...

Distributed actuation and control of a morphing tensegrity structure
Structures and actuation systems need to be closely integrated together in the future to create faster, more efficient, lightweight dynamic machines. Such actuated structures would be used for morphing aircraft wings...

Dynamic Deployment of a Minitab for Aerodynamic Load Control
Load control is the reduction of extreme aerodynamic forces produced by gusts, maneuvers, and turbulence to enable lighter, more efficient aircraft. To design an effective control system, the actuator's response in terms of...

Lift enhancement by means of small-amplitude airfoil oscillations at low Reynolds numbers
Force and particle image velocimetry measurements were conducted on a NACA 0012 airfoil undergoing small-amplitude sinusoidal plunge oscillations at a poststall angle of attack and Reynolds number of 10,000. With increasing...

Unsteady Lift and Moment of a Periodically Plunging Airfoil
To simulate the effects of gusts and maneuvers, lift, moment, and flow measurements are presented for a periodically plunging airfoil at a Reynolds number of 20,000 over a wide range of reduced frequency (k≤1.1), amplitude...

Unsteady Aerodynamics of a Plunging Airfoil in Transient Motion

The peak loads experienced by aircraft of all scales will typically be during gusts, turbulence or extreme manoeuvres. Understanding the aerodynamic response to these transient disturbances is therefore crucial, particularly...
