Abstract


The work introduces a preliminary design chain valid for hybrid-electric, full-electric, and thermal powered aircraft. From early stages of the design process, the integration of aero-propulsive interaction between propeller (or fan) slipstream and airframe is an important step to obtain trends and compare different aircraft. The present work integrates in the design chain both the distributed propulsion and tip-mounted propeller interactions, deriving for the latter effect a simple model suitable for point performance estimation. The research activity is oriented by market and political demands. Derived from these requirements, two different applications of the design process are proposed on FAR/CS-25 and FAR/CS-23 certified aircraft. Trends about the possible applications, benefits, and drawbacks show that, with the current technology state of the art, a full-electric aircraft is still unfeasible, unless a design range of 100 nmi is acceptable.
