Chris is a hands-on entrepreneur with over 20 years' experience in various companies. His interest is in developing, commercializable, usable products that are elegant, practical design solutions to problems unaddressed by current products in the marketplace. Engaged in a number of projects over the years, his current involvements are in Speelbelovend CV (carpentry, toy manufacturing and wholesale), Rail Pleasure Holding BV (first railbike company in the Netherlands), and Cormorant SEAplanes BV.
From making his first toy seaplane at the tender age of 6, aviation has been a passion all his life. Practical experience gained in the aviation environment has subsequently proven invaluable, for example:
As the originator of Cormorant, Chris follows a holistic approach in both conceptual design and aircraft analysis. With its original mission statement still valid, initially conceived to address design deficits in the general aviation amphibious aircraft sector, Cormorant has developed as a robust, adaptable, general aviation solution that capitalizes on developments in electric aviation to offer a solution that is substantially independent of the charging network and requires minimal infrastructure for its operation (with capability to operate from unpaved runways and water). It is thus not just a sustainable solution per se, its environmental operating requirements are less. Chris sees Cormorant as capable of also serving communities based in remoter locations, a segment of the population seemingly often overlooked in the development of e-aviation solutions.
Currently Chris is hands-on with the construction of the Cormorant prototype for ground / water trials and aerodynamic analyses. When time permits, he is happy to meet with interested parties to discuss the project.
As an aerospace engineer since the start of his working life in the late 1980s, Frank gained his knowledge and experience with renowned aerospace companies Fokker Aircraft, Collins Aerospace and Thales Avionics. He is now working as a consultant for ADSE Consulting and Engineering and in that capacity is supporting the Cormorant endeavor.
Over the years he has performed several roles in: avionics design; certification; engineering management; process development; and, organizational development and change. In the recent past as a member of a broader ADSE team, he has supported several aerospace start-ups, with a focus on rotorcraft and eVTOL. Specifically, Frank has contributed to organization development, aerospace process development, and training of a new generation of aerospace engineers. Frank is an EASA Form 4 holder and has for more than 10 years had the responsibility of being Head of Design for the EASA-approved ADSE Design Organization (DOA). He supports several other DOAs as Compliance Verification Engineer for avionics and electrics. Frank continues to be interested in new developments and innovative technologies, in particular around sustainable propulsion systems. He is intrigued by Cormorant’s technical and flight operational concepts, in particular its potential for providing a sustainable transport solution to a wide variety of markets and users.
Integration and certifiability of the new electric and / or hybrid propulsion technologies are two of the key interests for his support to Cormorant, topics that both have a high level of activity in the broader aerospace community. Frank has learned that strong and open cooperation with the authorities such as EASA and the FAA, and industry standard working groups such as EUROCAE, SAE and ASTM is key to certification of these new technologies. His ambition is to contribute to making Cormorant a versatile, adaptable, EASA CS-23 certified aircraft that is cost effective, and an attractive market proposition.
ADSE is an independent engineering and consulting firm supporting the aviation industry to achieve net-zero ambitions by investing in the development of new technology and knowledge, and developing sustainable aerospace propulsion systems (hybrid, electrical, hydrogen) and novel aircraft architectures. ADSE supports various initiatives in the industry and is proud to act as a sponsor to the Cormorant initiative.
After tertiary education, receiving a first-class honors degree in Chemistry from the University of Edinburgh and an MBA from (Alliance) Manchester Business School, Mark worked for several blue-chip companies, including BP Oil International, Royal Bank of Scotland, and Price Waterhouse. He then bought-in to an aircraft component manufacturer in the early 1990s since when, he:
Koos commenced his piloting career at the age of 19, when he earned his military aviator’s wings with the Royal Netherlands Navy. Shortly after, he was selected for training and became qualified to operate from the Dutch Colossus Class aircraft carrier, HNLMS Karel Doorman.
Following this period as a naval aviator and flight instructor, Koos transferred into civil aviation as an Airline Transport Pilot. Over the following fifty-five years Koos was involved in flying all types of aircraft in both operational and technical projects; he has over 34,000 flight hours’ experience on a wide range of large and small civilian and military aircraft.
The various types of flying Koos has been involved with include:
Though no longer actively, professionally flying, Koos maintains his passion for aviation through participation in specific projects.
Cormorant has provided the platform for Koos to re-establish previous encounter with Chris Rijff - they worked together, not knowing each other personally, at the same time on the Euro-ENAER "Eaglet" project in Den Helder; Koos also performed the maiden test flight of the Eaglet in Chile, the home country of this 'plane.
