Stability versus maneuverability in hovering flight [PDF]
Insects and birds are often faced by opposing requirements for agile and stable flight. Here, we explore the interplay between aerodynamic effort, maneuverability, and stability in a model system that consists of a Λ-shaped flyer hovering in a vertically oscillating airflow.

A study on using electric power steering to reduce the effort required for handling
This paper proposes a design method that uses electric power steering (EPS) to reduce the effort required for handling in a vehicle. To accomplish this, the design must reduce the physical effort required of the driver, improve the controllability of ...

High Maneuverability Lenticular Airship [PDF]
This paper presents and describes a new lenticular shaped airship that allows 3D omnidirectional movements. The airship is intended to be part of a cooperative aerial system based in the synergy between an airship and a group of micro-quad rotors capable of long time missions as environmental, biodiversity monitoring, WiSAR missions, road monitoring ...

Ship's Maneuverability in Strong Wind [PDF]
This paper deals with effect of wind forces and moment acting on the training ship SAE NURI. The results of drift angle and counter rudder angle due to wind effect are calculated by using the static equilibrium method especially with nonlinear mathematical expression, and then the critical wind velocity is found out.
