Chris Rijff

Head of Design

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:

  • By late 1998 Chris had become involved with Euro-ENAER in Den Helder in the Netherlands, a manufacturing start-up far a small trainer aircraft, The Eaglet. There he worked in testing, design and production support. He was also a manufacturer of production molds.
  • Chris was also an active participant in the building of molds and the interior design process for the SIMONA simulator, based at the Delft University of Technology (TUDelft).

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.

Frank Kaiser

Interim Head of Certification

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.

Fred Bouter

Cormorant Advisory Group - Advisor

Serendipity brought Fred and Cormorant together through pure coincidence. As he summarizes, “It’s fun to work with Cormorant’s people and slowly build on the team that is going to be required to support its aspirations.”

We have welcomed Fred as an Advisor to the Cormorant Advisory Group, where he provides a valued contribution through his network built up over many years in the general aviation sector.

With a varied career in nautical and aeronautical roles, Fred:

  • Acted for 5 years as a merchant navy officer onboard general cargo vessels and ocean-going tugboats.
  • As a Royal Dutch Navy Reserve Officer, he formed part of flight crews as navigator / observer / tactical coordinator on Lockheed Neptune and Grumman Tracker aircraft operating from shore- and carrier bases. Operations comprised both military activities and search & rescue missions.
  • As a trainee Air Traffic Controller with EUROCONTROL, he completed theoretical ATC training.
  • As a materials coordinator with a major oil company, he spent 4 years coordinating the materials and equipment despatched to the Arabian peninsula.
  • At Fokker Aircraft a role of Maritime Specialist was initially filled. Lack of sales of the Fokker F27 resulted in his transition to Executive Staff Officer Flight Crew Training and Operations Support. Promotion followed to Head of Flight Crew training and Operations Support a.i.
  • A short period at Fokker’s airworthiness department followed with further training in aircraft accident investigation. This was interrupted by having to prepare and execute ground training of flight crews for a military customer.
  • Fokker Aircraft’s demise saw a period of uncertainty, with part-time work undertaken for an engineering firm bringing contacts in the nuclear industry and for rigid airships.
  • Permanent employment followed with Air Traffic Control the Netherlands (LVNL) as Manager - Information & Documentation until retirement.

Retirement has proven to be anything but retiring, with Fred:

  • Committing to part-time care of a relative suffering illness.
  • Capitalising on contacts made at LVNL, starting up a general aviation operators’ conference that has developed into the Netherlands General Aviation Symposia.
  • Continuing his love of the sea, including sailing trans-Atlantic west to east, from Miami, Florida via the Bahamas, Bermuda, and the Azores, to Faro, Portugal.
