Abstract

Aerodynamic characteristics improvement of Quad Tilt Wing VTOL plane in cruise.

Reference URL

Please refer to ‘Four-engine tilt wing VTOL aircraft | Technology of VTOL/STOL | Aeronautical Technology Directorate‘.

Reasons for using JSS2

It takes a lot of time to calculate using workstation.

Achievements of the Year

Aerodynamic interference reduction method was studied from forward wing to backward wing of tandem wing using FaSTAR.
