Abstract: The Heliship - page 9 Described is a Rotary Wing Aircraft with an Oval shape fuselage body, Concave beneath, affixed with Anhedral wings enclosing a set of concealed Rotary wing blades joined to a central Hub. The Invention, herein called the Heliship, resembles a Fixed Wing Aircraft with non-visible from above, the Array of Rotary Wing blades connected to a central Hub enclosed and concealed beneath the device in a full length concave cavity. (demonstrated in Figs 1-2-3-4-5-6 drawings) Centrally placed Airshafts penetrate the fuselage (see Fig 2) from above down to the Rotary Array and from the sides and above the Wings where the Array extends. In motion, the airflow is encouraged to follow the underside of the fuselage to the Rotor blades, along the cavity, (as in Fig 2) of the accompanying drawings, and the rotors have significant space above to allow forward airflow to be drawn over and down into the rotors (which may be tilted either sideways, forward or backward) and then mixed with the added vortex airflow from the airshaft above. The Airflow characteristics displayed in Fig 2, play an essential part in the uniqueness of the airflow aerodynamics of the Heliship aerofoil shape fuselage, with the below body concavity enabling improved lifting Airflow into and around the Fuselage to the Rotary Array. The Wings shown are Dihedral, (see Fig 1) and at right angle to the fuselage at the front, and diminishing from the wingtip to a minimum, in a convex curved line to the rear, forming a triangular shape ending in a smaller concave cut-out section in the Wing structure. At the rear on either side of the fuselage, adjoining it may be seen a vertical stabiliser set at an angle away of 60 degrees, and rising to a height equal to the highest point of the fuselage. (Fig 2). The Wings merged with the fuselage, form an enveloping shape enclosing the Rotary Wing Array to provide for a Wing in Ground Effect (WIGE) in Flight capability. The design is a low centre of gravity Heliship, with increased stability, requiring no evident tail Rotor, as it has the benefit of flaperions, tail fin rudders, and elevators as does a winged Aircraft. The above features are designed to make the Aircraft particularly manoeuvrable, perform as a (VTOL) Vertical Take Off and Land vehicle, Hover and Fly slowly or fast as an Aircraft in an exceptionally controlled free flight way, or fly as a (WIGE) Wing in Ground Effect craft. The idea is to provide an Airflow efficient Aerodynamic Aircraft, with Rotary Wing ability, advantaged by a clear uninterrupted Air downwash. As an Aircraft it forms an anomaly, with a Fuselage more than twice as wide as conventional Aircraft, with Wings which merge into the Fuselage, curved forward and Anhedral in design, below which are the centrally mounted Rotary Wing blade Array. The design size of this Aircraft is limited by the possible length of a Rotary Wing blade; although multiple Array designs are plausible in other enlarged Aircraft forms. Aerodynamically, the idea of mounting Rotary Wing Array within a Streamline Aircraft body forms the crux of creating a versatile Aviators device to perform multi-tasks.
