Interview: Kimberly Slater of Draper Laboratory Discusses the Challenges of Hypersonic Flight

Parabolic Arc conducted a Q&A with Kimberly Slater, the Commercial and Science Space Lead at Draper Laboratory, about the guidance, navigational and control software she has worked on for Stratolaunch’s Talon-A hypersonic test vehicle.

Tell me a little about yourself, your engineer and career background and how you got to work for Draper.

Right now I currently lead our civil commercial science space work at Draper, but my history before Draper was all in human space flight. My engineering degree is in man machine interface design. And everything I did before Draper was building, developing, testing, and flying scientific experiments on the space shuttle and space station. So, I did everything from design and build to writing software, writing the interface training manuals to the software—the procedure that the astronauts use on orbit—and then I did crew training for both the American and Russian crew for both space station and shuttle and then mission support and then mission control centers in both Moscow and Houston to support the mission. You know that whole ‘Houston we have a problem’ question when things on orbit and any anomaly has happened during that real time fast paced mission support.

MOJAVE, Calif. — Stratolaunch’s Roc — the world’s largest airplane by wing span at 385 ft (117.3 m) — flew for the fourth time on Thursday. In a sign of just how complicated the massive air-launch platform is to fly, one of the main objectives of this flight test was to retract and lower the plane’s landing gear at altitude for the first time ever.

Stratolaunch Flight 4 Objective Today: Raise & Lower Landing Gear for First Time

Video Caption: Stratolaunch Lead Systems Engineer Stu Yun discusses preparation for the carrier aircraft’s fourth flight test, in which the team will retract and extend all of the aircraft landing gear for the first time.

Editor’s Note: The video spotlights some of the tradeoffs with advanced flying machines built by Burt Rutan and Scaled Composites. They are capable of very innovative designs that push the outside of the envelope on what can be done with airplanes and spacecraft. The tradeoff is that the vehicles can be quite complex and not the easiest things to operate or maintain. That it’s taking until the fourth flight to fully retract and extend all the landing gear is ample proof.

Stratolaunch Announces Research Contract with U.S. Air Force Research Laboratory

MOJAVE, Calif., January 25, 2022 (Stratolaunch PR) – Stratolaunch, LLC is pleased to announce a research contract with the U.S. Air Force Research Laboratory (AFRL).

Stratolaunch, under partnership with Booz Allen Hamilton, is on contract with AFRL to examine and assess the feasibility of hypersonic flight tests of a wide range of Air Force experiments and payloads on a frequent and routine basis.

Stratolaunch supports national security objectives for hypersonic offensive and defensive weapons development through the design, manufacture, and operation of a fleet of reusable hypersonic aerospace vehicles air-launched from its globally deployable carrier aircraft, Roc. The company plans to augment existing Department of Defense flight test resources through affordable, commercially contracted, rapid turnaround hypersonic flight testing for the Department of Defense and its prime contractor partners.

“Our goal is to provide affordable and routine access to the hypersonic flight environment,” said Dr. Daniel Millman, Chief Technology Officer for Stratolaunch. “We look forward to sharing lessons learned from this collaboration with AFRL, yielding powerful and practical research results benefiting the nation.”
