5 place Blended Wing and Body Personal Aircraft
The Atlantica is the state of the art in aeronautical, structural and process engineering. It is the long overdue application of existing proven aerospace technologies for private aircraft. The benefits are higher performance, lower cost and greater levels of safety than was ever possible with conventional design theory.
This general aviation blended wing and body (GA BWB) was created by programming the personal aircraft mission requirements into a modern simulator using the BWB format. The evolutionary results were a whole new family of exceptional air vessels. Criteria include high cruise speeds, stability, docile landings and roominess. The structures lend themselves to low parts count plus the strong and light characteristics of monolithic construction. Stall resistance, high impact strength and an all plane parachute are integral to the design.
Historically BWB’s have proven to be stable and efficient. Starting in 1944 with the Horten Bros. HO-9 in Germany to the modern day stealth B-2, 117B and military remote piloted craft BWB’s are finding many uses. The up to date hang gliders and research for future mega commercial planes also use this versatile configuration. Thanks to the Horten Bros. we have documentation as to the aerodynamics and rigging for high performance hands off stable flight of these craft that date back to the 30’s. New computers and software have just made it easier for us to tailor BWB’s to our present needs and new composites.
Aerodynamically it is neither a flying wing nor a Delta wing. This configuration is the pitch stable diamond wing combined with the yaw stable swept wing with winglets. It has the smooth ride and stall resistance of the canard type but the control authority of a conventional type. There is no drag due to wing to wing and wing to fuselage interference. The small winglets minimize tip vortices drag and increase the aspect ratio for even better climb and high altitude efficiency. The blending of wing and fuselage provides luxurious cabin, baggage and fuel space to the sides while minimizing external surface area. This "side" or lateral loading also solves the CG problems encountered with conventional designs. Most important is that no other configuration produces such low drag.
The Atlanticas sandwich composite structures are ideal. First of all the geometry maximizes strength for both flight and impact loads. Second the shape’s simplicity lends itself to be constructed from just a few large components each made in one step with monolithic pressure closed molds. This process requires far less materials, skill and man-hours to produce a higher quality airframe. Even tool up cost is substantially reduced by the simplicity and low parts count of the configuration.
This ideal aircraft resolves all the shortcomings that pilots have just "accepted" as necessary compromises. The Atlantica will prove that with today’s knowledge we can have high performance, affordable and safe personal flight transportation.
