fineness ratio

Most aircraft have fineness ratios significantly greater than this, however.

Fineness ratio is often applied to the entire vehicle, considering the overall length and diameter.

The fuselage was completely smooth, with a high fineness ratio for low drag at supersonic speeds.

As the fineness ratio increases, the wetted area, and thus the skin friction component of drag, is also going to increase.

With its low fineness ratio of 2.83, the ZMC-2 was difficult to fly.

An example of a high-performance design with an imperfect fineness ratio is the Lancair.

Missile designers are even less interested in low-speed performance, and missiles generally have higher fineness ratios than most aircraft.

Fineness ratio is a term used in naval architecture and aerospace engineering to describe the overall shape of a streamlined body.

Aircraft that spend time at supersonic speeds generally have high fineness ratios, a canonical example being Concorde.

In order to minimize the wave drag, the curvature of the aircraft should be kept to a minimum, which implies much higher fineness ratios.

This is not ideal for ballistics, especially supersonically where a higher fineness ratio is desirable.

The introduction of aircraft with higher fineness ratios also introduced a new form of instability, inertial coupling.

The ratio of the length of a nose cone compared to its base diameter is known as the fineness ratio.

Reducing the length of the fuselage would require larger controls, which would offset the drag savings from using the ideal fineness ratio.

The factors influencing the pressure drag are the general shape of the nose cone, its fineness ratio, and its bluffness ratio.

To do so, a designer can consider the fineness ratio, which is the length of the aircraft divided by its diameter at the widest point (L/D).

Therefore the minimum drag fineness ratio is ultimately going to be a tradeoff between the decreasing wave drag and increasing friction drag.

The aircraft had a long, thin fuselage with a high fineness ratio; a small tapered almost-rectangular wing was mounted centrally on the fuselage.

The Starfighter's fuselage had a high fineness ratio, i.e., it was slender, tapering towards the sharp nose, and had a small frontal area.

The Extended Nosecone was a long spike with a high fineness ratio that lowered atmospheric drag by creating shock waves that cleared the vehicle body during ascent.

At supersonic speeds, the fineness ratio has a significant effect on nose cone wave drag, particularly at low ratios; but there is very little additional gain for ratios increasing beyond 5:1.

It was only when the aircraft began to sacrifice aerodynamic surface area in order to lower drag, and use longer fineness ratios that lowered supersonic drag, that the effect became obvious.

Large engines at the front of the aircraft made it difficult to obtain a reasonable fineness ratio, and although wings could be made thin and broad, doing so made them considerably less strong.
