Before commercial micro-turbines were widely available, enthusiasts had to build their propulsion systems from scratch. Thomas Kamps democratized this process by publishing highly detailed technical guides. His work broke down complex aerodynamic and thermodynamic principles into formulas that an advanced hobbyist could utilize in a home workshop. The Standard Reference Manual
Kamps provides a unique system for builders who wish to modify the engine's size. Rather than providing a single rigid blueprint, This involves taking the diameter of their chosen compressor and dividing it by the diameter of the compressor used in Kamps' default design. The builder then multiplies the rest of Kamps' component measurements by this factor, providing a mathematically sound method to scale the entire engine up or down.
To understand why Kamps’ book is so highly sought after, one must understand the sheer complexity of a micro-turbine. A model jet engine operates on the exact same thermodynamic cycle (the Brayton cycle) as a full-sized Boeing 747 engine, compressed into a package roughly the size of a coffee thermos.

Thomas Kamps is a pioneer in the field of miniature gas turbines. In the early 1990s, he successfully simplified the daunting physics of jet propulsion into a format that a skilled machinist could replicate. His designs focused on using centrifugal compressors—often repurposed from automotive turbochargers—paired with handmade combustion chambers and turbine wheels.

The primary achievement of Kamps was the democratization of jet propulsion. Before the publication of his research and designs, high-performance model aircraft relied almost exclusively on piston engines or "ducted fans"—shrouded propellers that mimicked the look of a jet but lacked the genuine physics of a turbine. Kamps provided the blueprint for a functioning, centrifugal-flow gas turbine that could be built in a well-equipped home workshop. His designs, particularly those focusing on the KJ-66 turbine, served as the DNA for the commercial turbine industry that exists today.

This is a highly critical, precision-machined ring with angled vanes. If the diffuser is miscalculated, the engine will suffer from compressor stalls or fail to start. 3. The Combustion Chamber
