Driven by the desire for high subsonic flight, the major focus of aircraft engine development is on turbofan engines. However, the constant pursuit of higher propulsive efficiency redirected propulsion studies to the inherently more efficient turboprop propulsion system [1–3]. As a result, there is a renewed interest in open-rotor integration, ranging from wingtip-mounted distributed propulsion (eg the proposed NASA X-57 Maxwell concept [4]), tail-mounted open-rotors [5, 6], to tail-mounted single-rotating propellers. Tail-mounted propeller configurations are of interest primarily because of their potential to reduce the cabin noise compared to wing-mounted propellers [2]. Several studies [2, 7] have considered the feasibility of a number of tail-mounted propeller configurations, such as T-tail configurations with pylon-mounted propellers and integrated configurations with propellers mounted on the tip of the horizontal tailplane, as illustrated in Fig. 1.(a) Horizontal-tailplane mounted(b) Pylon mounted
