Transonic

Index Transonic

In aeronautics, transonic (or transsonic) flight is flying at or near the speed of sound (at sea level under average conditions), relative to the air through which the vehicle is traveling. [1]

Accretion (astrophysics)

In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk.

Aerodynamics

Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is the study of the motion of air, particularly its interaction with a solid object, such as an airplane wing.

Aeronautics

Aeronautics (from the ancient Greek words ὰήρ āēr, which means "air", and ναυτική nautikē which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere.

Anti-shock body

An anti-shock body (also known as Whitcomb body or Küchemann carrot) is a pod positioned on the leading edge or trailing edge of an aircraft's aerodynamic surfaces to reduce wave drag at transonic speeds (Mach 0.8–1.0).

Area rule

The Whitcomb area rule, also called the transonic area rule, is a design technique used to reduce an aircraft's drag at transonic and supersonic speeds, particularly between Mach 0.75 and 1.2.

Critical Mach number

In aerodynamics, the critical Mach number (Mcr or M*) of an aircraft is the lowest Mach number at which the airflow over some point of the aircraft reaches the speed of sound, but does not exceed it.

Dew point

The dew point is the temperature to which air must be cooled to become saturated with water vapor.

Hypersonic speed

In aerodynamics, a hypersonic speed is one that is highly supersonic.

Interstellar Boundary Explorer

Interstellar Boundary Explorer (IBEX) is a NASA satellite that is making a map of the boundary between the Solar System and interstellar space.

Jet engine

A jet engine is a type of reaction engine discharging a fast-moving jet that generates thrust by jet propulsion.

Mach number

In fluid dynamics, the Mach number (M or Ma) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.

Prandtl–Glauert singularity

The Prandtl–Glauert singularity is the prediction by the Prandtl–Glauert transformation that infinite pressures would be experienced by an aircraft as it approaches the speed of sound.

Prandtl–Meyer expansion fan

A supersonic expansion fan, technically known as Prandtl–Meyer expansion fan, is a centred expansion process that occurs when a supersonic flow turns around a convex corner.

Rotorcraft

A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast.

Solar wind

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.

Speed of sound

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.

New!!: Transonic and Speed of sound · See more »

Supersonic speed

Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1).

Swept wing

A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction.
