Extended Nose

The extended nose of a supersonic aircraft helps to shape the forward shock wave, ensuring smooth airflow and efficient aerodynamics.

Fixed Canard

Canard surfaces are small wings located on the nose of the aircraft, these surfaces are fixed for the QueSST and provide nose-up trim specifically at the low boom design point.

Inlet Shock Shielded by Wing

The wing of the QueSST is designed to protect the intake of the engine from shockwaves, this ensures a smooth flow of air into the engine for efficient operation.

Single Piece Wing Skins

Single piece wing skins are used on the QueSST, which enhances structural integrity and efficiency in stress distribution.
