Supersonic aircraft are poised for a comeback. Current regulations do not permit supersonic flight over land due to sonic boom noise. However, recent advances in simulation-based design are opening the door to new supersonic aircraft designs with reduced sonic boom impacts. The design of these aircraft requires accurate predictions of sonic boom on the ground and techniques for shaping the aircraft to achieve a desired boom signature while maintaining performance.
This webinar details how Pointwise and SU2 can be used to tackle supersonic aircraft design. Watertight surface and volume
We will also demonstrate how to formulate and solve a shape design problem in SU2, using a continuous adjoint formulation to obtain the sensitivities for gradient-based optimization. This includes a discussion of proper settings for the flow and adjoint problems, objectives and constraints, FFD design variables, and mesh deformation. Finally, we will present optimal shape design results from SU2 for the Lockheed Martin 1021 aircraft.

Lockheed Martin 1021The Lockheed Martin 1021 is one of the test cases from the AIAA 1st Sonic Boom Prediction Workshop. At that website, you will find the technical paper Full Configuration Low Boom Model and Grids for 2014 Sonic Boom Prediction Workshop by J. M. Morgenstern, M. Buonanno, and F. Marconi (AIAA Paper 2013-0647).
Travis Carrigan joined Pointwise as a senior engineer after completing his M.S. in aerospace engineering at The University of Texas at Arlington in May 2011 where his graduate research involved aerodynamic design optimization. Currently, as Manager of Technical Sales, Mr. Carrigan works with prospective customers and demonstrates how Pointwise software can be used to improve their CFD process. He also produces technical marketing content and works with customers and software partners to demonstrate best practices in grid generation, solver setup, and solution post-processing for a variety of industries.

Trent Lukaczyk is a Ph.D. candidate in the Aerospace Design Lab within the Department of Aeronautics & Astronautics at Stanford University. His core research interests are in aircraft design and optimization methods, and he is currently contributing to the design of NASA's next-generation supersonic passenger jet. This work depends on experience in various disciplines that he gained during several internships and his undergraduate education at Cornell University: developing meshing tools, simulating the aerodynamics of both aircraft and automobiles, testing those designs in the wind tunnel, and designing combustion engines.
