Genzken's exhibition begins with lumps of plaster and model troglodyte dwellings, window-like objects framing emptiness, and a number of sleek, highly crafted things: pointed, aerodynamic-looking forms that thrust this way and that on the floor.
Those questions, dealing with the craft's aerodynamic stability, are being reviewed by an expert panel appointed late last year by William S. Cohen, then the secretary of defense.
Virgin Galactic's first SpaceShipTwo was destroyed on Oct. 31, 2014, when a co-pilot prematurely unlocked the feathers during a powered test flight and aerodynamic forces broke the craft apart.
If Reynolds is the current embodiment of the quintessential Star sailor, it's also because, by profession, he's a sailmaker whose business is crafting the aerodynamic wings on which the fastest Stars fly.
Although he was able to correct this, the system that runs the aerodynamic control surfaces of the craft subsequently malfunctioned.
A stall can occur when the plane's nose points upward at too great an angle, robbing the craft of the aerodynamic lift that allows it to stay aloft.
The whole process is controlled from a cockpit, which is also designed to be retractable to allow the craft to be as aerodynamic as possible.
craft (ACVs); the latter are called aerodynamic ground-effect machines (GEMs).
The former are classed as aerostatic craft (ACVs); the latter are called aerodynamic ground-effect machines (GEMs).
An alternative formulation, applied in marine and air craft fluid dynamics, of the traditional aerodynamic derivatives model, is presented.
Mr. Faget, drawing on aerodynamic principles established by the scientist Harvey Allen, designed a craft that looked, Mr. Chaikin said, "more like an inverted Styrofoam coffee cup with a saucer-shaped lid," which re-entered the atmosphere blunt end first.
