NASA HYPERSONIC INFLATABLE TECH TEST SET FOR VIRGINIA LAUNCH JULY 21

WALLOPS ISLAND, Va. -- NASA Space Technology Program researchers will
launch and deploy a large inflatable heat shield aboard a rocket
travelling at hypersonic speeds this weekend during a technology
demonstration test from the agency's Wallops Flight Facility on
Wallops Island, Va.

NASA has four consecutive days of launch opportunities for the
agency's Inflatable Re-entry Vehicle Experiment (IRVE-3), starting
July 21, with the liftoff window from 6 a.m. to 8 a.m. EDT each day.

The test is designed to demonstrate lightweight, yet strong,
inflatable structures that could become practical tools for
exploration of other worlds or as a way to return items safely to
Earth from the International Space Station. During this technology
demonstration test flight, NASA's IRVE-3 payload will try to re-enter
Earth's atmosphere at hypersonic speeds -- Mach 5, or 3,800 mph to
7,600 mph.

"As we investigate new ways to bring cargo back to Earth from the
International Space Station and innovative ways to land larger
payloads safely on Mars, it's clear we need to invest in new
technologies that will enable these goals," said Michael Gazarik,
director of NASA's Space Technology Program. "IRVE-3 is precisely the
sort of cross-cutting technology NASA's Space Technology Program
should mature to make these future NASA and commercial space
endeavors possible."

The IRVE-3 experiment will fly aboard a three-stage Black Brant XI
launch vehicle for its suborbital flight. The payload and the heat
shield, which looks like a large, uninflated cone of inner tubes,
will be packed inside the rocket's 22-inch-diameter nose cone. About
six minutes after launch, the rocket will climb to an altitude of
about 280 miles over the Atlantic Ocean.

At that point, the 680-pound IRVE-3 will separate from the rocket. An
inflation system similar to air tanks used by scuba divers will pump
nitrogen gas into the IRVE-3 aeroshell until it becomes almost 10
feet in diameter. Instruments on board, including pressure sensors
and heat flux gauges, as well as cameras, will provide data to
engineers on the ground of how well the inflated heat shield performs
during the force and heat of entry into Earth's atmosphere.

After its flight, IRVE-3 will fall into the Atlantic Ocean about 350
miles down range from Wallops. From launch to splash down, the flight
is expected to take approximately 20 minutes.

"We originally came up with this concept because we'd like to be able
to land more mass and access higher altitudes on Mars," said Neil
Cheatwood, IRVE-3 principal investigator at NASA's Langley Research
Center in Hampton, Va. "To do so you need more drag. We're seeking to
maximize the drag area of the entry system. We want to make it as big
as we can. The limitation with current technology has been the launch
vehicle diameter."

Cheatwood and a team of NASA engineers and technicians have spent the
last three years addressing the technical challenges of materials
withstanding the heat created by atmospheric entry and preparing for
the IRVE-3 flight. The team has studied designs, assessed materials
in laboratories and wind tunnels, and subjected hardware to thermal
and pressure loads beyond what the inflatable spacecraft technology
should face during flight.

This test is a follow on to the successful IRVE-2, which showed an
inflatable heat shield could survive intact after coming through
Earth's atmosphere. IRVE-3 is the same size as IRVE-2, but has a
heavier payload and will be subjected to a much higher reentry heat.

IRVE-3 is part of the Hypersonic Inflatable Aerodynamic Decelerator
(HIAD) Project within the Game Changing Development Program, part of
NASA's Space Technology Program. Langley developed and manages the
IRVE-3 and HIAD projects.

Journalists interested in attending the IRVE-3 launch at NASA's
Wallops Flight Facility should contact Wallops Public Affairs Officer
Keith Koehler at 757-824-1579 or [email protected] to arrange
for media accreditation.

Commentators are saying there are on board cameras and we should be able to watch the inflation. Certainly sounds worth tuning in for. :)

NASA SUCCESSFULLY TESTS HYPERSONIC INFLATABLE HEAT SHIELD

WALLOPS ISLAND, Va. -- A large inflatable heat shield developed by
NASA's Space Technology Program has successfully survived a trip
through Earth's atmosphere while travelling at hypersonic speeds up
to 7,600 mph.

The Inflatable Reentry Vehicle Experiment (IRVE-3) was launched by
sounding rocket at 7:01 a.m. Monday from NASA's Wallops Flight
Facility on Wallops Island, Va. The purpose of the IRVE-3 test was to
show that a space capsule can use an inflatable outer shell to slow
and protect itself as it enters an atmosphere at hypersonic speed
during planetary entry and descent, or as it returns to Earth with
cargo from the International Space Station.

"It's great to see the initial results indicate we had a successful
test of the hypersonic inflatable aerodynamic decelerator," said
James Reuther, deputy director of NASA's Space Technology Program.
"This demonstration flight goes a long way toward showing the value
of these technologies to serve as atmospheric entry heat shields for
future space."

IRVE-3, a cone of uninflated high-tech rings covered by a thermal
blanket of layers of heat resistant materials, launched from a
three-stage Black Brant rocket for its suborbital flight. About 6
minutes into the flight, as planned, the 680-pound inflatable
aeroshell, or heat shield, and its payload separated from the launch
vehicle's 22-inch-diameter nose cone about 280 miles over the
Atlantic Ocean.

An inflation system pumped nitrogen into the IRVE-3 aeroshell until it
expanded to a mushroom shape almost 10 feet in diameter. Then the
aeroshell plummeted at hypersonic speeds through Earth's atmosphere.
Engineers in the Wallops control room watched as four onboard cameras
confirmed the inflatable shield held its shape despite the force and
high heat of reentry. Onboard instruments provided temperature and
pressure data. Researchers will study that information to help
develop future inflatable heat shield designs.

After its flight, IRVE-3 fell into the Atlantic Ocean off the coast of
North Carolina. From launch to splashdown, the flight lasted about 20
minutes. A high-speed U.S. Navy Stiletto boat is in the area with a
crew that will attempt to retrieve IRVE-3. The Stiletto is a maritime
demonstration craft operated by the Naval Surface Warfare Center
Carderock, Combatant Craft Division, and is based at Joint
Expeditionary Base Little Creek-Ft Story, Va.

"A team of NASA engineers and technicians spent the last three years
preparing for the IRVE-3 flight," said Lesa Roe, director of NASA's
Langley Research Center in Hampton, Va. "We are pushing the
boundaries with this flight. We look forward to future test launches
of even bigger inflatable aeroshells."

This test was a follow-on to the successful IRVE-2, which showed an
inflatable heat shield could survive intact after coming through
Earth's atmosphere. IRVE-3 was the same size as IRVE-2, but had a
heavier payload and was subjected to a much higher re-entry heat,
more like what a heat shield might encounter in space.

IRVE-3 is part of the Hypersonic Inflatable Aerodynamic Decelerator
(HIAD) Project within the Game Changing Development Program, part of
NASA's Space Technology Program. Langley developed and manages the
IRVE-3 and HIAD programs.

This 10-ft ring weighed 680 lbs.

What would a standard ablative (PICA or similar) heat-shield of equilavent size weight ?

Congrats to everyone involved on the IRVE III / Cheatwood 39.011 project!

I was able to wake up a bit early and catch the launch from WFF island. Due to a very low ceiling we were only able to see about the first 2 or 3 seconds of first stage burn. I did, however, manage to see the first stage impact the ocean. I've attached some pictures that a coworker took.

From the video, it seemed to hit about 285 miles apogee, Black Brant has some serious power.

One of my first thoughts about this earlier this morning was...  "that would be perfectfor spacex recovery if they wanted to go with the whole dr. no/evil joke."

On a more serious note, did they have to choose the Stiletto because they had only a vague idea where the craft would reenter and the Stiletto's speed gave them a huge range for recovery?  Or do the Navy SEALS just have the day off so they decided to loan out one of their babies. ;)
