Flow over aerospace vehicles and through jet engines are very challenging to compute due to the complex geometries and turbulent flow physics at high Reynolds numbers.  The potential offered by large eddy simulations (LES) to compute transitional and turbulent flows has been well-known for many years. That potential may be finally realized with the development of adaptive high-order methods capable of handling complex geometries. In this talk, we will examine key factors affecting the quality of solutions obtained with LES, and review recent progresses in the development of the flux reconstruction (FR)/correction procedure via reconstruction (CPR) method into a LES tool for the design of aerospace vehicles:

• High-order discontinuous methods
• High-order mesh generation
• Efficient time marching
