How to select the correct compressor map for model aircraft applications.
When hobbyists look for a Thomas Kamps PDF or physical copy, they are usually looking for practical, math-backed solutions to extreme engineering limitations. Kamps addressed several hurdles that previously prevented micro-turbines from working safely: Rotor Dynamics and Balancing
Online communities focused entirely on DIY gas turbines.
Before Kamps and fellow pioneer Kurt Schreckling, jet-powered models were considered "too complex and too much trouble". Kamps proved that through careful matching of components rather than just high-level precision manufacturing, an amateur could achieve a thrust-to-weight ratio comparable to a full-size aircraft engine.

Designing the diffuser vanes to efficiently convert high-velocity kinetic energy into static pressure. 3. The Combustion Chamber Design model jet engines thomas kamps pdf
One of Kamps' most famous breakthroughs was utilizing readily available automotive turbocharger compressor wheels (such as those from Schwitzer or KKK turbos). The book explains:
While the concept of building a miniature jet engine from scratch might seem like the ultimate project for a model maker, Thomas Kamps' book has consistently proven that it is a deeply rewarding endeavor. As the successor to Kurt Schreckling's pioneering book on the FD3/64, Kamps' work brought the construction and operation of gas turbines up to date with modern techniques and components.
While Kamps’ work is timeless in its theory, the context of model aviation has changed. Today, most modelers buy pre-made turbines. However, the Kamps methodology remains essential for safety. Understanding the stresses involved in a turbine spinning at 100,000+ RPM is mandatory. The PDF serves as a safety manual, warning of the catastrophic potential of burst disks or bearing failures.

However, it's important to know that the design is over 25 years old. While historically significant, it is relatively compared to modern hobby turbines, which can reach over 130,000 RPM.
, where a small percentage of turbine fuel (Kerosene or Jet-A mixed with synthetic oil) is diverted directly through the bearings for cooling and lubrication. 4. The Turbine Wheel and NGV
Thomas Kamps is a German engineer and author who revolutionized the hobbyist approach to jet propulsion. Before the advent of cheap, commercially available RC turbine engines (like JetCat or KingTech), building a jet engine was considered impossible for an amateur. Kamps demystified the process.

The Turbine Wheel extracts energy from the exhaust gas to drive the compressor. The Nozzle Guide Vane (NGV) straightens and accelerates the gas flow before it hits the wheel. Kamps provides exact geometry for these components, which must withstand gas temperatures exceeding 700°C (1,292°F). What to Expect Inside the Document
Engineering students utilize the book as a real-world case study in thermal dynamics and fluid flow modeling. Safety and Modern Operational Considerations
Thomas Kamps’ Model Jet Engines remains a holy grail text for a reason. It bridges the gap between complex aerodynamic theory and practical, garage-built mechanics. Whether you are an engineering student looking to understand micro-propulsion, a vintage RC enthusiast looking to build a classic turbine from scratch, or a modern jet pilot wanting to understand the physics of your $3,000 ready-to-fly engine, studying Kamps' foundational principles is the best place to start.
How air is compressed, mixed with fuel, ignited, and accelerated to create usable thrust.
Thomas Kamps' is considered a foundational text in the hobby of miniature gas turbine construction. Originally published in German as Modellstrahltriebwerke , it was translated into English and became a go-to resource for enthusiasts looking to build or understand small-scale turbojets.
