Prandtl Wing

As scientists continue to wrestle with the vexing trouble of how to get humans to Mars and bring them safely habitation, robotic exploration of the Red Planet has already yielded many amazing discoveries. However, our missions to the planet's surface accept studied only a tiny fraction of the land area, and rovers aren't likely to become much faster in the future. NASA has only completed preliminary testing on a novel fly blueprint that could one day allow a Mars probe to soar through the planet's thin temper and cover smashing distances.

In that location are ii projects operating in tandem, both based on the aforementioned high-lift boomerang-shaped wing design. There's the Preliminary Inquiry Aerodynamic Design to Lower Drag (Prandtl-d) and the forward-looking Preliminary Research Aerodynamic Design to Land on Mars (Prandtl-m). NASA scientists have been testing the Prandtl-d design for some fourth dimension at present, merely it has only recently been subjected to a full battery of wind tunnel tests. This is essential to understand how the wing will perform in a variety of conditions, including those on Mars if the blueprint is carried over to a space mission.

The current of air tunnel calibration model testing of Prandtl-d was carried out jointly by NASA'south Armstrong Flying Center and Langley Inquiry Eye. According to the data, the boomerang wing is remarkably stable, fifty-fifty when it's completely stalled. That could save a Mars exploration aeroplane from a catastrophic failure when information technology'due south a few million miles away from the nearest repair crew. The airflow patterns over the boomerang wing proved to be totally new to the team, which could account for its ability to generate loftier lift and remain stable.

Prandtl-d test

The adjacent pace for Prandtl-one thousand is a loftier altitude test of the fly pattern that volition have place later on this year. A small prototype of the plane will be released at an altitude of 100,000 feet. The temper up that high is a close approximation of Mars, so information technology's important to know if Prandtl-m could generate enough lift to stay aloft in such conditions. If the test goes well, that could be huge for future Mars missions.

NASA doesn't look it will accept to pattern an entire mission around Prandtl-m. The beauty of this design is that it could ride to Mars in a 3U CubeSat (about one foot square) connected to the aeroshell of a Mars rover. This module could be ejected when the rover begins its descent, allowing the airplane to deploy and wing a tremendous distance before gliding to the surface. It could exist used for geological surveys, imaging, and scouting future landing sites upward shut. The additional weight of the Prandtl-m craft wouldn't add much of anything to the launch price either.

NASA believes Prandtl-d could morph into Prandtl-m in fourth dimension for inclusion on the 2022-era Mars rover. That mission could attain the Crimson Planet as soon as 2022-2024.
