What does high-speed low drag mean?

Adverb. high-speed low-drag (not comparable) (informal) Highly efficiently or competently.

What does high drag mean?

A low drag coefficient implies that the streamline shape of the vehicle’s body is such as to enable it to move easily through the surrounding viscous air with the minimum of resistance; conversely a high drag coefficient is caused by poor streamlining of the body profile so that there is a high air resistance when the …

What does low drag mean in the military?

It literally just means “cool”, “awesome”, etc. High-speed, low-drag is an aerodynamic term first popularized and used as buzz words when the military started introducing jet aircraft which were, compared to their predecessors and contemporaries, high-speed, and had low-drag.

What does high speed mean in the military?

The full expression is “High speed, low drag”. What it means is someone who is efficient, capable, motivated and has the ability to encourage others to do their best. It has nothing to do with any particular MOS and can apply to anyone in or out of the military.

Which is better a higher or lower drag coefficient?

A low coefficient is conducive to high top speed and low fuel consumption, while a higher drag coefficient is generally found in cars searching for high cornering speeds influenced by downforce. It shows that a car’s coefficient of drag can be found by analysing the drag force acting on the car at a given speed.

What does high speed mean in military?

High Speed – A term that can be positive or negative depending on the context. It can be a service member who is highly motivated but also sarcastically for someone who isn’t. Joe – A junior enlisted soldier. Mandatory Fun – An event required by service members to attend, it’s never actually fun.

How do you say I understand in military?

Roger That. “OK,” “Understood,” and “Yes, sir/ma’am” are all acceptable replacements for this military phrase. The general public will understand what you mean if you do slip up, but it is not a common saying among civilians.

Is 0.3 A good drag coefficient?

The average modern automobile achieves a drag coefficient of between 0.25 and 0.3.

What is the best drag coefficient?

The electric Mercedes EQS is the world’s most aerodynamic production car. Its 0.20 drag coefficient beats the Tesla Model S and Lucid Air.

What type of wings have low induced drag?

Long, thin (chordwise) wings have low induced drag; short wings with a large chord have high induced drag. Wings with an elliptical distribution of lift have the minimum induced drag. Modern airliners use winglets to reduce the induced drag of the wing.

What is the drag coefficient in aerodynamics?

The Drag Coefficient The drag coefficient is a number that aerodynamicists use to model all of the complex dependencies of shape, inclination, and flow conditions on aircraft drag. This equation is simply a rearrangement of the drag equation where we solve for the drag coefficient in terms of the other variables.

What is drag due to lift and induced drag?

It is also called “drag due to lift” because it only occurs on finite, lifting wings. Induced drag occurs because the distribution of lift is not uniform on a wing, but varies from root to tip. For a lifting wing, there is a pressure difference between the upper and lower surfaces of the wing.

How do you find the drag coefficient at zero lift?

The total drag coefficient Cd is equal to the drag coefficient at zero lift Cdo plus the induced drag coefficient Cdi . The drag coefficient in this equation uses the wing area for the reference area. Otherwise, we could not add it to the square of the lift coefficient, which is also based on the wing area.
