What is an EM diagram?

What is an EM diagram?

Energy-Maneuverability Diagram. An aircraft performance comparison method developed by USAF Colonel John Boyd that incorporates energy, thrust, weight, aerodynamic drag, wing area, flight characteristics and more.

What are energy maneuverability methods?

It relates the thrust, weight, aerodynamic drag, wing area, and other flight characteristics of an aircraft into a quantitative model. This allows combat capabilities of various aircraft or prospective design trade-offs to be predicted and compared.

How do you calculate specific excess power?

Specific excess power: Thrust power (TV ) minus the drag power (DV ) divided by the weight.

What is aircraft maneuverability?

Maneuverability is defined as the ability to change the aircraft flight path by application of forces from the rotors or other control devices. 5 In other words, maneuverability is the measure of the maximum achievable time rate of change of the velocity vector at any point in the flight envelope.

What is the most feared aircraft?

Currently, the one fighter that easily takes the cake is the U.S. Air Force F-22 Raptor stealth fighter. The F-22 jet was originally designed to take on the best of the Soviet Union’s fighters in air-to-air combat, as in this role is easily the world’s deadliest air superiority fighter.

What is excess power?

The difference between the power available and the power required at a particular speed and height. It is a measure of the rate of climb and acceleration.

What is VX and VY?

VX and VY are arguably the two most important V speeds in all of aviation. VX is the best angle of climb and VY is the best rate of climb. In most cases, VY is used because it gets the plane to altitude the fastest. But if you need to climb more steeply, then VX is the best airspeed to use.

Can you store electricity in water?

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine.

Is unused electricity wasted?

This includes: Waste heat occurring due to inefficiencies in the process of converting primary energy to electricity. This makes up about 54% of the overall losses….How Much Primary Energy Is Wasted Before Consumers See Value from Electricity?
