AIM
Aim of this presentation is give brief idea about swept wing configuration and its applications on super sonic
flight

INTRODUCTION
A wing planform favoured for high subsonic jet speeds.
To reduce the wave drag. first investigated in Germany from
1935 onwards. introduction of the MiG-15 and North
American F-86 .

Contd…
When aircraft enters the transonic speeds just below the speed of sound, an effect known as wave drag starts.
Near the speed of sound oblique shock wave is generated.
Shock waves require energy to form.

DRAG AND MACH NUMBER

Comparission

angle of sweep
which characterizes a swept wing is conventionally measured along the 25% chord line.

Varient of Design features
forward sweep

Forward swept wing
Allowing more space in generally cramped corporate jet cabins
Relatively expensive. Highly maneuverable at transonic
speeds

Swept back Design
![Page 13: Swept wing configuration](https://reader036.fdocuments.net/reader036/viewer/2022081418/5562697dd8b42aed7d8b5240/html5/thumbnails/13.jpg)
Sweptback wing
Extra lateral stability. Longitudinally stable on its own. Delay the compressibility effect
when flying at transonic speed.

Variable-sweep wing
Also known as swing wing. That may be swept back and then
returned to its original position during flight.

Advantages
Aeroelastically enhanced maneuverability
Smaller basic lift distribution
Increased trailing edge sweep for given structural sweep - lower CDc
Unobstructed cabin
Easy gear placement
Good for turboprop placement

Disadvantages
Aeroelastic divergence or penalty to avoid it
Lower Cnβ (yaw stability)
Bad for winglets
Stall location (more difficult)
Reduced pitch stability due to additional lift and fuse interference
