Draper Excels As GNC Flight Software Supplier In Stratolaunch's Historic Talon A-1 Flight

Draper's guidance, navigation and control (GNC) flight software was instrumental in the successful first powered flight of Stratolaunch's Talon-A hypersonic test vehicle.

Cambridge, MA /PRNewswire-PRWeb/ - Draper, a leading provider of flight systems for space, missile, hypersonic and defense programs, is proud to announce its role as a flight software supplier for the successful first powered flight of Stratolaunch's Talon-A test vehicle, TA-1.

The inaugural powered Talon-A1 took flight on March 9, 2024, marking a major milestone in the development of the country's first privately funded, reusable hypersonic test capability. Draper designed, developed, tested and delivered the guidance, navigation and control (GNC) software that supported the TA-1's autonomous operation.

Stratolaunch builds, tests and operates hypersonic vehicles—those that can travel at least five times the speed of sound, or Mach 5. Draper's flight software was used on Talon-A, a fully reusable, autonomous, liquid rocket-powered Mach 6-class hypersonic vehicle.

The TA-1 flight is the second flight of the Talon-A vehicle model, following the successful unpowered TA-0 drop-test on May 13, 2023, also flown using Draper's GNC solution.

"Hypersonic flight testing requires robust, agile and modular approaches," said Dan Gallton, Ph.D., director of space navigation and in-space servicing, assembly and manufacturing (ISAM) for Draper's Space Systems program office. "Draper delivered GNC flight software designed for Stratolaunch's hypersonic test platforms while successfully managing evolving requirements in vehicle equipment, flight scenarios and mission parameters, demonstrating once again the durability of Draper's GNC flight software."

Primary objectives for the flight test included accomplishing safe air-launch release of the TA-1 vehicle, engine ignition, acceleration, sustained climb in altitude and a controlled high-speed flight. "The flight test demonstrated that Draper's GNC flight software gave TA-1 exceptional levels of control under challenging conditions, including slow flight, fast supersonic flight and two periods of transonic flight—one accelerating, one decelerating," said Ravi Gondhalekar, Ph.D., an aerospace guidance and control research engineer and senior member of the technical staff at Draper.

"Draper has been a great partner to Stratolaunch as we have completed two successful flights of the Talon-A vehicle," said Brian Pincock, Talon-A Vehicle Management System Lead. "Draper's experience and the quality GNC flight software produced by their team were integral to these achievements in the advancement of hypersonic technology maturity."

Draper's flight software expertise has its roots in the Apollo Program, and since then the company has developed GNC solutions for the Space Shuttle, the International Space Station, Artemis and a range of civil, commercial and national security customers.
