Aircraft designers commit significant resources to the design of aircraft in meeting performance goals. Despite fulfilling traditional design requirements, many fighter aircraft have encountered buffet loads when demonstrating their high angle-of-attack maneuver capabilities. As a result, during test or initial production phases of fighter development programs, many new designs are impacted, us...

Buffeting is an aeroelastic phenomenon which plagues high performance aircraft, especially those with twin vertical tails, at high angles of attack. Previous wind-tunnel and flight tests were conducted to characterize the buffet loads on the vertical tails by measuring surface pressures, bending moments, and accelerations. Following these tests, buffeting estimates were computed using the measu...

Wing morphing as a means to continuously modify wing geometry is employed in numerical simulation order act upon aerodynamic performance cruise flight. In this flight regime, the interaction of shock wave and boundary layer instabilities can lead transonic buffet, coordinated motion both detached layer. This flow instability induces unsteady forces on which may induce dip-flutter or cause stall...

In contrast to a focus on efficiency, we advocate aggressive usage of available resources. This view is embodied in what we call the Buffet principle: continue using more resources as long as the marginal cost can be driven lower than the marginal benefit. We illustrate through several examples how this seemingly obvious principle is not adhered to by many common designs and how its application...

OBJECTIVE Each day, tens of millions of restaurant goers, conference attendees, college students, military personnel, and school children serve themselves at buffets--many being all-you-can-eat buffets. Knowing how the food order at a buffet triggers what a person selects could be useful in guiding diners to make healthier selections. METHOD The breakfast food selections of 124 health confere...

OBJECTIVE To evaluate the nutritional composition of worksite canteen lunches and to examine the impact of two meal serving systems on employee intake, i.e. buffet style with a fixed price for a varied number of dishes and à la carte style with a separate price for each item on the menu. DESIGN Laboratory technicians observed employees' food selection and collected identical dishes. Food item...

In 2013, an outbreak of gastrointestinal illness occurred following a buffet lunch at a restaurant in Canberra. An investigation was conducted to identify the cause of illness and to implement appropriate public health measures to prevent further disease. We conducted a retrospective cohort study via telephone interviews, using a structured questionnaire developed from the restaurant buffet men...

The aim of this present study was to determine the reliability of a buffet-type meal as a measure of spontaneous energy and macronutrient intake. In addition, we evaluated the short-term effects of diet on the composition of the substrate mix oxidized postprandially. Fourteen male subjects had ad libitum access to a variety of foods from a buffet-type meal offered in the laboratory during two i...
