Can NASA's F-15D help make supersonic jets quieter?

NASA’s Armstrong Flight Research Center (AFRC) in California has issued a formal Request for Information (RFI) seeking help in producing at least one flight-ready aerodynamic test pod to fly aboard the agency’s F-15D jet for supersonic aircraft research.

AFRC is soliciting information from potential sources to provide engineering support, manufacturability analysis, fabrication, assembly, inspection, and delivery of at least one flight-ready aerodynamic test pod (with an option for a second pod). The test pod will support the agency’s Flight Demonstration and Capabilities Subproject - Geometry Optimization and Sensing with Integration and Flight Test (GoSWIFT). GoSWIFT is a NASA-supported research project exploring the feasibility of quieter commercial supersonic aircraft.

Test Pod Objective

Initiated in July 2023 under a NASA Cooperative Agreement, the project involves Texas A&M University, the University of Michigan, Utah State University, Boeing Research and Technology, and NASA.

The RFI states the objective is to design, manufacture, and deliver an aerodynamic test pod that maintains the Outer Mold Line of a standard centerline 610-gallon external fuel tank used on an F-15D aircraft. The pod will support aerodynamic and flight test activities while providing internal volume for instrumentation and test equipment.

“Interested firms having the required capabilities necessary to meet the above requirement described herein should submit a capability statement,” NASA said in the RFI. No solicitation exists currently; therefore, “do not request a copy of the solicitation.” All responses must be submitted no later than March 20.

“This synopsis [RFI] is for information and planning purposes only and is not to be construed as a commitment by the government nor will the government pay for information solicited,” NASA added.

The primary mission of GoSwift is to advance technologies that minimize the "sonic boom" noise associated with supersonic flight. Quieter supersonic aircraft travel is a growing area of research in the aerospace industry.

Sonic Boom Over Land

In October, Lockheed Martin Skunk Works-built X-59 experimental aircraft completed its maiden flight, moving the world a significant step closer to the return of widespread commercial supersonic travel. The X-59 jet: developed in partnership with NASA, is not merely a fast jet; it is a technological effort to overcome the primary barrier that has grounded supersonic passenger flight over land for decades: the disruptive noise of the sonic boom.

Overcoming the Sonic Barrier

Since the retirement of the Concorde and regulatory actions taken worldwide in the early 1970s, supersonic flights have been restricted over land due to the intense pressure wave created when an aircraft exceeds the speed of sound—the deafening noise commonly known as the sonic boom. This restriction effectively strangled the viability of supersonic commercial air travel.

The X-59, often referred to as the centerpiece of NASA’s Quesst mission, is designed specifically to mitigate this issue.
