Project Helicopter
CVH
The
final graduation focussed on the conceptual design of the helicopter. After a period
at a famous foreign Aircraft manufacturer company, the aerospace faculty
desired a new impulse into design methods for helicopters.
The
specification
of the CVH (Civil Helicopter) was based on the Seaking. What do we need
as a possible replacement for this famous Sikorsky helicopter? The
Dutch
National Aerospace Laboratory (NLR) was involved in the H4 project and
provided
assistance. The design work was done at the Delft University of
Technology/ Dept. of Aerospace Engineering, commonly known as
"Vliegtuigbouw".
The CVH project
concentrated both on the conceptual design itself as well as on predictive methodologies.
A computer
program was developed to calculate rotor design characteristics and performance
using "rotor blade theory". The method includes the complicated flapping of the
blades, the airfoil shape and all the stability effects on the helicopter
itself. The system is still in use today. The CVH project took over 15
months to complete.
