Project Helicopter H4
After makiing some conceptual aircraft designs, why not getting interested in THE helicopter, a relatively unknown subject at the faculty?
Being offered a chance to do a conceptual design study on the lay out of a future European helicopter at the Dutch National Aerospace Laboratory (NLR) , got into it! The design was part of the starting up European NH90 project.
The project looked at various constraints as dictated by market requirements on size and a three dimensional Computer Aided Design system was used. The CAD system was quite new at the time at Delft University. Computer CPU requirements were that large that during the night, three systems running on VAX machines were used, feeding up to 95% of total Delft University VAX mainframe resources into the system.
The H4 design was calculated and engineered using laboratory engineering methods. Some methods came from the CVH project.
The final design was used in the subsequent stages of the NH90 but later on it turned out that this configuration was not selected.
