However, potential energy can easily be traded for kinetic energy, so an aircraft with an altitude advantage can easily turn the potential energy into speed. Instead of applying thrust, a pilot may use gravity to provide a sudden increase in speed, by diving, at a cost in the potential energy that was stored in the form of altitude.
The United States Air Force Stability and Control DATCOM is a collection, correlation, codification, and recording of best knowledge, opinion, and judgment in the area of aerodynamic stability and control prediction methods. [1]
By the late 1970s, the Air Force had developed a 10-year energy reduction plan for its facilities under the Energy Policy and Conservation Act. It also created the first Air Force Energy Office at Tyndall Air Force Base, Florida, which became the focal point for all of the service’s energy matters and policies.
OEA develops, implements, and oversees an integrated facility energy portfolio, including privately financed, large-scale renewable and alternative energy projects as well as direct Air Force investments. [3] OEA leverages partnerships [4] with the Army's Office of Energy Initiatives and the Navy’s Resilient Energy Program Office.
The Air Force is the largest user of fuel energy in the federal government. The Air Force uses 10% of the nation's aviation fuel. (JP-8 accounts for nearly 90% of its fuels.) This fuel usage breaks down as such: 82% jet fuel, 16% facility management and 2% ground vehicle/equipment. [4] To meet renewable energy goals, the Air Force plans to ...
Energy–maneuverability theory is a model of aircraft performance. It was developed by Col. John Boyd , a fighter pilot, and Thomas P. Christie , a mathematician with the United States Air Force , [ 1 ] and is useful in describing an aircraft's performance as the total of kinetic and potential energies or aircraft specific energy .
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
