A study on using electric power steering to reduce the effort required for handling

open access: yesNihon Kikai Gakkai ronbunshu, 2016
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]

open access: yes, 2012
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]

open access: yesJournal of Navigation and Port Research, 2008
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.

High Maneuverability Airframe: Investigation of Fin and Canard Sizing for Optimum Maneuverability [PDF]

open access: yes, 2014
Abstract : The next generation of precision munitions is likely to use a non-rolling airframe with 4 independent canards to increase maneuverability of the munition such that it can engage moving as well as stationary targets. The design of such a precision munition requires increased understanding of the airframe, of maneuver technology, and of ...
