The first zero G plane to enter service in Latin America is a T-39 Sabreliner nicknamed CONDOR, operated for the Ecuadorian Civilian Space Agency and the Ecuadorian Air Force since May 2008. [14] On June 19, 2008, this plane carried a seven-year-old boy, setting the Guinness world record for the youngest person to fly in microgravity. [15]
In an airplane, the pilot's seat can be thought of as the hand holding the rock, the pilot as the rock. When flying straight and level at 1 g, the pilot is acted upon by the force of gravity. His weight (a downward force) is 725 newtons (163 lb f). In accordance with Newton's third law, the plane and the seat underneath the pilot provides an ...
The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1]
The metabolic cost of transport includes the basal metabolic cost of maintaining bodily function, and so goes to infinity as speed goes to zero. [1] A human achieves the lowest cost of transport when walking at about 6 kilometres per hour (3.7 mph), at which speed a person of 70 kilograms (150 lb) has a metabolic rate of about 450 watts. [1]
Zero Gravity "G-FORCE ONE" aircraft People in the reduced-gravity aircraft. As of August 2022, the price of a flight for a single passenger starts at US$8,200. [12] The unique Weightless Weddings Experience is also included in the list of services [13] Noah and Erin Fulmor were the first couple to get married in weightlessness. [14]
As noted earlier, , =,. The total drag coefficient can be estimated as: = [()], where is the propulsive efficiency, P is engine power in horsepower, sea-level air density in slugs/cubic foot, is the atmospheric density ratio for an altitude other than sea level, S is the aircraft's wing area in square feet, and V is the aircraft's speed in miles per hour.
ZFW is also defined as OEW + PL. The previous formula becomes: + =. For many types of airplane, the airworthiness limitations include a maximum zero-fuel weight. [1] This limitation is specified to ensure bending moments on the wing roots are not excessive during flight. When the aircraft is loaded before flight, the zero-fuel weight must not ...
The range equation reduces to: = where =; here is the specific heat constant of air 287.16 J/kg K (based on aviation standards) and = / = (derived from = and = +). c p {\displaystyle c_{p}} and c v {\displaystyle c_{v}} are the specific heat capacities of air at constant pressure and constant volume respectively.
