Gas turbine Technology

“It has been a fascinating 33 years in the world of micro-turbojets since Jerry Jackman made his first flight in 1983. The pace of the development seems to only be accelerating, not only in the jet propulsion industry but also power generation sectors. The next 20 years promise to bring even more excitement to the radio control jet modeler.” – Paul D Marsh

Cape Aerospace Technologies aspires to not only build high precision propulsion systems, but to also enrich and develop abilities in this specific industry. A key component of the company is to establish a knowledge transfer between engineer and artisan. CAT makes use of the latest software packages to design and optimize their turbines. These software include CAD, CAM, CFD, FEA and turbine cycle design packages.

CAT featured in the following articles to date:

+ Dataweek

+ CSIR

+ CSIR Annual Report 2014-2015

+ Advances in Defence & Security

Since 2009, a number of students have started doing research on micro gas turbines at the University of Stellenbosch, South Africa, gaining knowledge and insight into turbomachinery. The micro gas turbines and turbine related equipment used by the students are supplied by CAT. CAT is also responsible for all gas turbine testing at the University of Stellenbosch.

The interest in micro gas turbines has grown considerably at the University of Stellenbosch due to the exposure given to the students in collaboration with CAT. Research and investigations on micro gas turbine components such as the compressor and diffuser have started in 2009 at the University of Stellenbosch and have included the combustion chamber, turbine nozzle guide vanes and turbine rotor in recent years as the research and studies have grown; and are continuing to grow in scope and knowledge.

Below is a list of studies conveyed on micro gas turbines at the University of Stellenbosch since 2009.

CAT, together with the CSIR and the University of Stellenbosch have made remarkable technical achievements by getting the first new gas turbine prototype running in South Africa since the late 1980’s. CAT also delivered a 200 N gas turbine to AISI for display, as seen in the picture at the AAD Airshow.
