Chapter 3 Propulsion Systems for UAVs

Advanced Propulsion Systems for UAVs

Unlock the full spectrum of UAV propulsion design with this 131-page, graduate-level guide that combines rigorous theory and production-ready code. You’ll start by mastering thrust–drag balances, propeller momentum theory, and power-endurance trade-offs, then bring them to life with ready-to-run MATLAB scripts for Otto-cycle thermodynamics, electric-UAV endurance modeling, and BLDC motor–ESC–propeller thrust calculations . Next, deepen your toolkit with fully commented C++ examples for high-performance simulations of generator and turboshaft dynamics, choked-flow intake analysis, and Laval-nozzle exit conditions—perfect for embedding directly into flight controllers . You’ll also explore piston vs. turbine engines, carburetion vs. fuel-injection systems, and fuel-air mixing schematics, all underpinned by detailed thermodynamic cycle derivations. Scattered throughout are 25+ high-resolution diagrams, end-of-chapter problem sets, and comprehensive formula appendices that bridge academic models and real-world UAV workflows. Whether you’re an aerospace engineer optimizing drone endurance, an R&D professional validating engine designs, or an instructor seeking classroom-ready assets, this course delivers the theory, visuals, and hands-on tools you need to propel your UAV projects to new heights.
