Model jets spin between 100,000 and 160,000 RPM. At these speeds, a fraction of a milligram of imbalance will destroy the ceramic bearings instantly. Kamps provides explicit instructions on dynamic balancing using home-built rigs.
Are you planning to from raw metal stock, or are you looking to repair an existing commercial turbine ?
A specific highlight of Kamps’ work is his focus on the fuel system. Unlike glow-plug engines, jets require high-pressure fuel atomization. Kamps details the design of the atomizing nozzle and the fuel pump systems required to deliver kerosene at the precise pressure and spray pattern needed for ignition.
At 120,000+ RPM, even a microgram of imbalance will cause catastrophic bearing failure or explosive disassembly. Builders must construct or buy a dynamic balancer to balance the integrated shaft, compressor, and turbine wheel assembly.
First published in 1995, Thomas Kamps' "Model Jet Engines" quickly became a cornerstone reference for the hobby. Its timing was perfect; it appeared alongside Kurt Schreckling's pioneering work on the FD3/64 engine, which had demonstrated that a functional gas turbine could be built by a determined amateur in a home workshop. Kamps' book served as the ideal modern companion, bringing the construction and operation of these small gas turbines up to date. model jet engines thomas kamps pdf
Are you looking to or troubleshoot a commercial engine ?
Because the book is considered a standard text, it is widely referenced in university courses and engineering forums.
Kamps’ work breaks down the incredibly complex physics of a gas turbine into manageable, engineered sections. A standard model jet engine consists of five core stages: 1. The Compressor Stage Draws in ambient air and pressurizes it.

Modern model jets use ceramic hybrid bearings, electronic fuel metering, and often machined-from-solid billet turbine wheels (thanks to affordable 5-axis CNC). However, Kamps' Model Jet Engines remains relevant because:
It includes advice on why a prototype might fail, helping builders debug their projects. Important Considerations for Builders
Kamps’ book serves as both a theoretical textbook and a practical machining manual. If you are analyzing the contents of the classic text, it generally breaks down into several critical engineering phases: 1. Aerodynamic and Thermodynamic Foundations
