Design
The Starship is noteworthy for its carbon fiber composite airframe, canard design, lack of centrally located vertical tail, and pusher engine/propeller configuration.
Carbon fiber composite was used to varying degrees on military aircraft, but at the time the Starship was certified, no civilian aircraft certified by the US Federal Aviation Administration had ever used it so extensively. Beech chose carbon fiber composite for its durability and high strength-to-weight ratio. According to Beech, the Starship weighs less than it would have if it were built from aluminum. Nonetheless, the empty weight of production aircraft exceeded the target by several thousand pounds.
Beech studied several configurations before settling on a canard configuration in early 1980. As configured, the Starship is difficult to stall—the forward surface stalls before the main lifting surface, which allows the nose to drop and more-normal flight to resume.
A traditionally located vertical tail would have transmitted propeller noise into the airframe. In its place, directional stability and control is provided by rudders mounted in the winglets (Beechcraft called them tipsails) at the tips of the wings.
Mounting the engines so that the propellers are facing rearward, pushing rather than pulling the aircraft, has the potential of a quieter ride since the propellers are further from the passengers and because vortices from the propeller tips do not strike the fuselage sides. However, the propellers are operating in a turbulent airflow in the pusher configuration (due to airflow past the wings moving aft in vortex sheets) and high-velocity exhaust gasses are discharged directly into the props, thus the resulting external propeller noise is more choppy and raucous than otherwise would be the case.
Flight instrumentation for the Starship included a 14-tube Proline 4 AMS-850 "glass cockpit" supplied by Rockwell Collins, the first application of an all-glass cockpit in a business aircraft.

Famous quotes containing the word design:
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
