Aerodynamic Analysis: Peter Sharpe's NeuralFoil

The performance data shown here is generated using NeuralFoil, an advanced aerodynamic engine developed by Peter Sharpe as part of the AeroSandbox project.

How it Works

NeuralFoil is a deep neural network trained on millions of XFoil simulations. It replicates the viscid-inviscid coupled panel method results with near-instantaneous speed, providing critical design data including \\(C_l\\), \\(C_d\\), and \\(C_m\\).

The Database Sweep

This database was generated using a high-fidelity model size (large) at incompressible speeds (Mach 0.00) and a critical N-factor of 9.0. The sweep covers a wide range of Reynolds numbers to ensure accuracy across scales.
