Testing inflatable heat shields for spacecraft

Engineers at NASA’s Langley Research Center in Hampton, Virginia, are developing inflatable heat shield technology called a Hypersonic Inflatable Aerodynamic Decelerator that could be vacuum packed into a rocket, then expanded in space to allow more cargo or even humans to land on distant planets, like Mars. Here they are testing the packing of a 9-foot diameter donut-shaped test article to simulate what would happen before a space mission.

New NASA X-Plane Construction Begins Now

NASA’s aeronautical innovators are ready to take things supersonic, but with a quiet twist.

For the first time in decades, NASA aeronautics is moving forward with the construction of a piloted X-plane, designed from scratch to fly faster than sound with the latest in quiet supersonic technologies.

The new X-plane’s mission: provide crucial data that could enable commercial supersonic passenger air travel over land.

To that end, NASA on April 2 awarded a $247.5 million contract to Lockheed Martin Aeronautics Company of Palmdale, Calif., to build the X-plane and deliver it to the agency’s Armstrong Flight Research Center in California by the end of 2021.

“It is super exciting to be back designing and flying X-planes at this scale,” said Jaiwon Shin, NASA’s associate administrator for aeronautics. “Our long tradition of solving the technical barriers of supersonic flight to benefit everyone continues.”

The key to success for this mission – known as the Low-Boom Flight Demonstrator – will be to demonstrate the ability to fly supersonic, yet generate sonic booms so quiet, people on the ground will hardly notice them, if they hear them at all.

Current regulations, which are based on aircraft speed, ban supersonic flight over land. With the low-boom flights, NASA intends to gather data on how effective the quiet supersonic technology is in terms of public acceptance by flying over a handful of U.S. cities, which have yet to be selected.

The complete set of community response data is targeted for delivery in 2025 to the Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO) from which they can develop and adopt new rules based on perceived sound levels to allow commercial supersonic flight over land.

Years of sonic boom research, beginning with the X-1 first breaking the sound barrier in 1947 – when NASA was the National Advisory Committee for Aeronautics – paved the way for the Low-Boom Flight Demonstration X-plane’s nearly silent treatment of supersonic flight.

The answer to how the X-plane's design makes a quiet sonic boom is in the way its uniquely-shaped hull generates supersonic shockwaves. Shockwaves from a conventional aircraft design coalesce as they expand away from the airplane’s nose and tail, resulting in two distinct and thunderous sonic booms.

But the design’s shape sends those shockwaves away from the aircraft in a way that prevents them from coming together in two loud booms. Instead, the much weaker shockwaves reach the ground still separated, which will be heard as a quick series of soft thumps – again, if anyone standing outside notices them at all.

It’s an idea first theorized during the 1960s and tested by NASA and others during the years since, including flying from 2003-2004 an F-5E Tiger fighter jetmodified with a uniquely-shaped nose, which proved the boom-reducing theory was sound.

NASA’s confidence in the Low-Boom Flight Demonstration design is buoyed by its more recent research using results from the latest in wind-tunnel testing, and advanced computer simulation tools, and actual flight testing.

Recent studies have investigated methods to improve the aerodynamic efficiency of supersonic aircraft wings, and sought to better understand sonic boom propagation through the atmosphere.

Even a 150-year-old photographic technique has helped unlock the modern mysteries of supersonic shockwave behavior during the past few years.

“We’ve reached this important milestone only because of the work NASA has led with its many partners from other government agencies, the aerospace industry and forward-thinking academic institutions everywhere,” said Peter Coen, NASA’s Commercial Supersonic Technology project manager.

So now it’s time to cut metal and begin construction.

The X-plane’s configuration will be based on a preliminary design developed by Lockheed Martin under a contract awarded in 2016. The proposed aircraft will be 94 feet long with a wingspan of 29.5 feet and have a fully-fueled takeoff weight of 32,300 pounds.

The design research speed of the X-plane at a cruising altitude of 55,000 feet is Mach 1.42, or 940 mph. Its top speed will be Mach 1.5, or 990 mph. The jet will be propelled by a single General Electric F414 engine, the powerplant used by F/A-18E/F fighters.

A single pilot will be in the cockpit, which will be based on the design of the rear cockpit seat of the T-38 training jet famously used for years by NASA’s astronauts to stay proficient in high-performance aircraft.

Jim Less is one of the two primary NASA pilots at Armstrong who will fly the X-plane after Lockheed Martin’s pilots have completed initial test flights to make sure the design is safe to fly.

“A supersonic manned X-plane!” Less said, already eager to get his hands on the controls. “This is probably going to be a once-in-a-lifetime opportunity for me. We’re all pretty excited.”

Less is the deputy chief pilot for Low-Boom Flight Demonstration. He and his boss, chief pilot Nils Larson, have already provided some input into things like cockpit design and the development of the simulators they will use for flight training while the aircraft is under construction.

“It’s pretty rare in a test pilot’s career that he can be involved in everything from the design phase to the flight phase, and really the whole life of the program,” Less said.

The program is divided into three phases and the tentative schedule looks like this:

2019 – NASA conducts a critical design review of the low-boom X-plane configuration, which, if successful, allows final construction and assembly to be completed.

2021 – Construction of the aircraft at Lockheed Martin’s Skunk Works facility in Palmdale is completed, to be followed by a series of test flights to demonstrate the aircraft is safe to fly and meets all of NASA’s performance requirements. The aircraft is then officially delivered to NASA, completing Phase One.

2022 – Phase Two will see NASA fly the X-plane in the supersonic test range over Edwards to prove the quiet supersonic technology works as designed, its performance is robust, and it is safe for operations in the National Airspace System.

2023 to 2025 – Phase Three begins with the first community response test flights, which will be staged from Armstrong. Further community response activity will take place in four to six cities around the U.S.

All of NASA’s aeronautics research centers play a part in the Low-Boom Flight Demonstration mission, which includes construction of the demonstrator and the community overflight campaign. For the low-boom flight demonstrator itself, these are their roles:

Ames Research Center, California — configuration assessment and systems engineering.

Armstrong Flight Research Center, California — airworthiness, systems engineering, safety and mission assurance, flight/ground operations, flight systems, project management, and community response testing.

Glenn Research Center, Cleveland — configuration assessment and propulsion performance.

Langley Research Center, Virginia — systems engineering, configuration assessment and research data, flight systems, project management, and community response testing.

“There are so many people at NASA who have put in their very best efforts to get us to this point,” said Shin. “Thanks to their work so far and the work to come, we will be able to use this X-plane to generate the scientifically collected community response data critical to changing the current rules to transforming aviation!”

Retired Major General Finds Balance as NASA Engineer

In many ways, the military and NASA couldn’t be different. Frank Batts has managed to navigate both worlds with precision, grace and just a bit of humor. After serving as a major general in the Army National Guard, he made the transition to working on computers as an engineer at NASA’s Langley Research Center in Hampton, Virginia.

“They’re opposites, but that keeps me balanced,” Batts said. “In the Army, you’re out there blowing things up in the field. Here, you’re trying to build electronic computer components.”

Batts is a senior data-systems engineer with the Advanced Measurement and Data Systems Branch at NASA’s Langley Research Center in Hampton, Virginia. He has been at Langley for 34 years and has seen the tools of the job change.

“Technology has changed tremendously,” said the 63-year-old Batts. “When we started out in the eighties, we were all using proprietary operating systems on real-time computers that were not widely used or understood. Now we’re pretty much using PCs for our work.”

In addition to his NASA career, Batts served his country with distinction in the armed forces – and made history along the way. He retired from the Army National Guard in 2012 as a major general and commander of the 29th Infantry Division in Fort Belvoir, Virginia - the first African-American to hold that post. He also served in the West Virginia and Tennessee national guards.

The adventure begins

Batts’ journey started in 1976, when he was accepted at North Carolina Agricultural and Technical State University in Greensboro and joined the Army Reserve Officer Training Corps (ROTC) there.

While at the university, Batts entered a cooperative program with the Union Carbide Corp., working in a gaseous diffusion plant in the nuclear division. After graduating from North Carolina A&T, Batts worked fulltime as an electrical engineer with Union Carbide, and as an engineering officer in the West Virginia National Guard.

“Initially when you get out of college, you’re competing with engineers from other schools,” Batts said. “I found out pretty soon that regardless of what school you came from, it got down to who can really deliver projects on time and on budget.”

Batts was pursuing a master’s degree in electronics engineering at North Carolina A&T around the time IBM introduced personal computers. He was told PCs were a fad and not worth investing in, but he glimpsed the future and got on board.

“It looked like to me it was the way to go,” he said.

But then in 1979, the Three Mile Island nuclear power plant in Pennsylvania experienced a partial core meltdown, releasing radioactive gas into the atmosphere.

The incident changed his professional trajectory, as the Union Carbide-run K-25 facility in Oak Ridge, Tennessee, where Batts was working, enriched uranium for nuclear power plants.

“Prior to Three Mile Island there were plans to construct nuclear plants all over the country, and K-25’s future was secure,” Batts said. “After Three Mile Island, all of those plans were dropped; we had more enriched uranium than was needed and K-25 was slated for closure.”

That meant he needed another job. While looking to move on, Batts found that NASA Langley was using a computing system similar to the one he used while he was with Union Carbide. He sets his sights on Langley, and has been on center as an electronic engineer since 1984 .

Two worlds in one

Batts’ military and NASA worlds were peacefully cohabitating until the Sept. 11, 2001, terrorist attacks. Batts was soon activated and from May 2004 through April 2005, served with the 54th Field Artillery Brigade Headquarters as the mobile liaison team chief in Kabul, Afghanistan as part of Operation Enduring Freedom.

“With the Army comes the leadership responsibilities. I managed a few thousand troops, and that’s no fun. I make an effort in my career at NASA to stay on the technical side rather than on the administrative side of things,” he said with a laugh.

What is fun for Batts, besides getting in more rounds at the golf course in his spare time, is serving as an example for engineering students though NASA’s outreach programs.

Batts, as the first engineer in his family, said he realizes the importance of recognizing those who blazed the trail for others.

“I have to pay homage to the people who came before me,” he said. “Before I was able to command a battalion, there was some else who commanded one, and did a credible enough job so that I had an opportunity.”

Batts also enjoys the reaction of people when they learn he works for NASA.

“There’s a lot of prestige that goes with working at NASA,” he said. “When people find out you work at NASA, they seem to look at you a bit differently.”

Brothers Bring Curious Minds, Sharp Questions to Langley

One brother is a facts-and-figures guy, the other an adventurer.

They're both deeply fascinated by all things space.

Mikey and Robbie Rouse, 15 and 16, are from Salem, Virginia, and both have Duchenne Muscular Dystrophy, a progressive condition that affects nearly all their voluntary muscles.

On a recent trip to Hampton, Virginia, they visited one of the birthplaces of the American space program — NASA's Langley Research Center.

Mikey, the adventurer, wants to be the first wheelchair astronaut. "And I want to go to Mars," he said during his visit.

Robbie, the facts-and-figures guy, is always thinking of safety first — a quality held sacred by all at NASA.

The brothers' visit to Langley included a tour of the center's hangar, a stop at the Flight Mission Support Center for the ozone-monitoring Stratospheric Aerosol and Gas Experiment III, and presentations on the Hypersonic Inflatable Aerodynamic Decelerator, autonomous technologies, and tests at the Landing and Impact Research Facility.

Deputy Center Director Clayton Turner and Associate Director Cathy Mangum presented Mikey and Robbie with commemorative coins and copies of "A Century at Langley," a pictoral history of the center.

No subject raised during the visit failed to spark the boys' curiosity.

Steve Velotas, associate director for intelligent flight systems, talked with Mikey and Robbie about the ways in which Langley researchers are studying autonmous technologies. Autonomous systems could be used in unmanned aerial vehicles, in-space assembly robots, or even wheelchairs to help those with disabilities navigate more easily.

"I don't trust robots completely," Mikey said.

"We don't either," said Velotas, who then explained that part of the reason Langley scientists are studying autonomous systems is to make sure they work like people want them to.

Evan Horowitz, structures and mechanical systems airworthiness engineer, showed the brothers Langley's historic hangar and talked about some of the past and present missions the facility has supported.

Gemini and Apollo astronauts trained in the hangar's Rendezvous Docking Simulator, and aircraft used for airborne science studies and autonomous flight research are based there.

Mikey and Robbie peppered Horowitz, who often takes tour groups through the hangar, with questions about air pollution and habitable exoplanets.

"This is great," said Horowitz. "Best interaction I've had in months."

The previous day, Mikey and Robbie visited the Virginia Air & Space Center, Langley's official visitors center.

The brothers live with their great-grandmother in Salem and receive daily assistance from a nonprofit called Lutheran Family Services of Virginia. The trip to Hampton was organized by Julie's Abundance Project, a program of Lutheran Family Services of Virginia.

At Hangar, Raptors Find Shelter from the Storm

As Tropical Storm Hermine charged up the East Coast Sept. 2, 2016, Langley Air Force Base reached out to the Research Services Directorate and NASA Langley Research Center hangar manager Dale Bowser to see if NASA Langley could store a few F-22 Raptors. Even though the hangar in Hampton, Virginia, already had a large visitor — a C-130 from the Wallops Flight Facility on Virginia’s Eastern Shore — the hangar was able to carefully sandwich in more than a dozen Air Force fighters and offer them protection from the wind. NASA Langley photographer David C. Bowman captured the image using a fish-eye lens and shooting down from the hangar's catwalk some 70 feet above the building's floor.

The hangar provides 85,200 square feet (7,915 square meters) of open space and large door dimensions that allow for entry of big aircraft such as Boeing 757s and other commercial or military transport-class planes. The hangar normally is home to 13 of NASA Langley's own research aircraft, when they are not out doing atmospheric science or aeronautics research. Still, there is enough space to share with neighboring Langley Air Force Base during emergencies. The facility is rated for at least a Category 2 hurricane. Built in the early 1950s, it was designed to fit a B-36. It can also accommodate the Super Guppy, which visited NASA Langley in 2014.
