Neural Air Data Sensing and Control for Hypersonic Vehicles 

Accurate Automation Corporation 

Chattanooga, TN 

Accurate Automation has developed a flush air data sensor comprised of a pressure- sensitive pad and a neural network module that can replace the pitot tube-based systems that provide air data on today’s aircraft

• Developed a neural network-based flush air data sensor subsystem which provides:
• Reduced drag
• A smaller radar signature
• Increased reliability
• Improved aircraft safety
• Performed wind tunnel tests to train the system and to validate the data received

• As the flush air data sensor can replace the pitot tube air data systems currently in use, the potential market is every aircraft manufacturer.  Because the system is flush with the body of the aircraft, maintenance costs are reduced because there is no tube that can be damaged by ground personnel.
• Accurate Automation has applied for a patent on this technology.
• Accurate Automation is in negotiation with a major aerospace firm for production of this product.

• This system can be used on all military and commercial aircraft.
• The National Transportation Safety Board has expressed interest in this technology because the system eliminates the danger posed by objects damaging or taping over a pitot tube.
