Abrégé

The invention relates to an aircraft (1), in particular an aircraft with support surfaces (11, 12), comprising a hull (10) for receiving at least one pilot and/or a payload, in particular air freight and/or at least one passenger, and at least one jacketed propeller drive (14) that has a propeller (20) with a hub body (21) and a plurality of rotor blades (22) which are distributed about the outer circumference of the hub body (21) in a uniform manner and which are invariably connected to the hub body (21) and have a blade tip at the radial outer end of the blade. The propeller (20) can be rotated about a drive axis (A) and is designed to be operated at a substantially constant rotational speed (n) over the entire operating range of the jacketed propeller drive (14). Furthermore, the jacketed propeller drive (14) has a jacket housing (36) which extends coaxially about the drive axis (A) of the propeller (20) and receives the propeller (20) and which defines a variable outlet cross-section (15) at a drive jet outlet side (16) of the jacketed propeller drive (14), in particular in an interactive manner together with the hub body (21).

The invention relates to an aircraft and to a method for operating an aircraft (1), in particular an aircraft with support surfaces (11, 12), comprising a hull (10) for receiving at least one pilot and/or a payload, in particular air freight and/or at least one passenger, and at least one drive device (50), which has a controller (53), for supplying a drive power to at least one jacketed propeller drive (14). The jacketed propeller drive (14) has a propeller (20) with a hub body (21) and a plurality of rotor blades (22) which are invariably connected to the hub body (21), wherein the propeller (20) can be rotated about a drive axis and is designed to be operated at a substantially constant rotational speed over the entire operating range of the jacketed propeller drive (14).
