Multi-point Wing Planform Optimization via Control Theory
Multi-point Wing Planform Optimization via Control Theory
2015/7/2
This paper focuses on wing optimization via control theory using a multi-point design method. Based on the design methodology previously developed for wing section and planform optimization at a speci...
While aerodynamic prediction methods based CFD are now well estab lished, and quite accurate and robust, the ultimate need in the design process is to find the optimum shape which maximizes the ...

Sonority variation in Stochastic Optimality Theory: Implications for markedness hierarchies
Sonority variation Stochastic Optimality Theory
2014/4/25
Constraints based on the sonority scale and other markedness hierarchies have been formalized
in two different ways: as scale-partition constraint families, with a universally fixed ranking, and
as...
Lateral dynamic flight stability of hovering insects: theory vs. numerical simulation
Insect Hovering Lateral dynamic flight stability Averaged model Equations-of-motion Navier--Stokes simulation
2012/2/24
In the present paper, the lateral dynamic flight stability properties of two hovering model insects are predicted by an approximate theory based on the averaged model, and computed by numerical simula...
