Ivan Rademeyer, founder of Da Vinci Innovations Ltd
Ivan achieved a Bachelors degree and an Honours degree in mechanical engineering from the University of Pretoria, South Africa, as well as a Masters degree in mechanical engineering from the University of Natal.
He started his career in 1980 in the Department of Post and Telecommunication in South Africa where he worked on several projects in the Buildings and Mechanical Section, doing mostly air conditioning plant design. In 1985 he joined the CSIR where he worked in the Turbo-machinery Section.
In 1994 Ivan launched Aeroflo, a joint venture company between the CSIR and the AEC where he used his knowledge of analytical and experimental fluid mechanics to lead a team of engineers in the development of air intake filters for helicopters. Under his leadership, Aeroflo was awarded the prestigious South African Technology Top 100 award.
In 2001, Ivan joined the University of Pretoria as a senior lecturer where he taught Fluid Machines and Aerodynamics to the final year mechanical engineering students and post-graduate Aircraft Design and Flight Mechanics.
In July of 2002 he started his own consulting engineering company where he completed several diverse projects for clients in South Africa, New Zealand and the USA. In 2005 he relocated his company, Da Vinci Innovations Ltd, to New Zealand where he is still focusing on product development and consultation projects.
ACHIEVEMENTS
Whilst Mr. Rademeyer was CEO of Aeroflo the company excelled and some of their achievements were:
Ø Development of the world’s first low-pressure ejectors for extracting dust from helicopter filter cartridges, employing helicopter exhaust gas to drive the ejector for scavenging the filter.
Ø Winner of the national Technology Top 100 Award for 1996 in the Materials and Manufacturing (Products and Processes) category
Ø Qualified twice as finalist in the Top Product Award (1995 and 1996)
Ø Selected as sole supplier of the filter for Eurocopter’s EC-120 helicopter
Ø Selected as sole supplier of the filter for the Belgian Army’s Agusta A109BA helicopter
Ø Selected to design and develop the filter for the Agusta AB139.
PATENTS PENDING
METHOD AND DEVICE FOR MIXING GASES (99/3879)
Gases are mixed in a mixing device having an elongate, tubular mixing chamber (16). At an inlet end of the mixing chamber (16), an annular nozzle (15) directs a drive gas under pressure longitudinally into the chamber (16). Inwardly, and optionally also annularly outwardly of the nozzle (15), a passive drive gas is induced or entrained to flow into the chamber (16) and to mix with the drive gas. Entrainment and mixing are enhanced by providing an interface between the drive gas and the passive gas over a large area, proportionally to a circumference of the nozzle (15).
