Is there a good accessible book comparing Second World War propeller technology?
Short answerNo book receives an unqualified recommendation: one strong technical treatment assumes engineering knowledge, while a pictorial alternative explains too little.
NotesA useful comparison of wartime propellers needs enough engineering detail to explain how they differ. One technically strong book assumes something close to an engineering degree. Another has good photographs but little explanation beyond identifying the propeller's material. Neither provides the desired balance between accessibility and technical substance, and neither is named.
