Passive load alleviation bi-stable morphing concept

Buffet Load Alleviation

High performance aircraft are, by their very nature, often required to undergo manoeuvres involving high angles of attack. Under these conditions unsteady vortices emanating from the wing and the fuselage will impinge on the twin fins (required for directional stability) causing excessive buffet loads, in some circumstances, to be applied to the aircraft. These loads result in oscillatory stres...

Morphing Between Stable Matching Problems

In the stable roommates (SR) problem we have n agents, where each agent ranks all other agents in strict order of preference. The problem is then to match agents into pairs such that no two agents prefer each other to their matched partners, and this is a stable matching. The stable marriage (SM) problem is a special case of SR, where we have two equal sized sets of agents, men and women, where...

Morphing Segmented Wind Turbine Concept

A morphing segmented concept is proposed herein for future extreme-scale wind turbine systems. The morphing may be accomplished by using segmented blades connected by screw sockets and a tension cable system. At low wind and rotor speeds, the segmented blades are fully tensioned and set at high pitch to ensure start-up and maximum power at low speeds. At high rotor rpm, the cable tension can be...

The Meta-Morphing Model Used in TARGIT BI Suite

This paper presents the meta-morphing model and its practical application in an industry strength business intelligence solution. The meta-morphing model adds associations between measures and dimensions to a traditional multidimensional cube model, and thus facilitates a process where users are able to ask questions to a business intelligence (BI) system without the constraints of a traditiona...
