Proving Prandtl - with a twist!

Published on Dec 13, 2013

A group of college aerospace engineering students in the 2012-2013 Aeronautics Academy at NASA's Dryden Flight Research Center have proven German aerodynamicist Ludwig Prandtl's theory on how to overcome one of the thorny problems of flight -- adverse yaw due to induced drag -- without relying on rudders or complicated computerized flight controls to accomplish it. This student-produced video details the students' research, using a student-built subscale flying-wing sailplane that proved that proverse yaw can be achieved just as birds achieve it -- through wingtip aerodynamics alone.

NASA Armstrong PRANDTL-D interns, summer 2015

Published on Aug 21, 2015

A group of NASA interns from different colleges across the nation came together during Summer 2015 with one goal: the successful flight test of PRANTDL-2. This student-produced video details the students' journey from fabrication to flight test of the PRANDTL-2 subscale aircraft. The students also worked on preparing the successor aircraft, PRANDTL-3, for flight tests later this year.

PRANDTL-D No. 3 takes flight

Published on Oct 29, 2015

NASA's Preliminary Research Aerodynamic Design to Lower Drag (PRANDTL-D) No. 3 aircraft successfully flew its first flight on Oct. 28, 2015. This flight test is the first of many that are aimed at improving flight efficiency. Engineers estimate future aircraft could see more than a 30 percent increase in fuel economy. The new wing design eliminates the weight & drag of the modern aircraft tail and its flight control surfaces.

The Mars airplane live event- Al Bowers on PRANDTL-M

Published on Mar 4, 2016

On October 16, 2015, students (from middle school to university levels), young professionals and members of the general public had an opportunity to participate in a live event where they learned about the possible first Mars airplane. During “The Mars Airplane Live Event”, keynote speaker and NASA Armstrong Chief Scientist Albion Bowers explained the inspiration for the PRANDTL-M (Preliminary Research AerodyNamic Design to Land on Mars) airplane. Mr. Bowers educated the audience on Mars and how PRANDTL-M may be the first airplane to glide through the Martin atmosphere. Mr. Bowers also explained the crucial role that NASA interns play in the development of PRANDTL-M. The event was jointly hosted by AIAA, AERO Institute and NASA Armstrong Flight Research Center.

PRANDTL-M successful test flights

Published on Nov 3, 2016

Preliminary AerodyNamic Design to Land on Mars (Prandtl-m) is a student developed NASA educational research activity to build a prototype glider for Mars flight. Designed to fit within a 3U cubesat and fly in the Martian atmosphere, Prandtl-m has some unique challenges. This video covers some of the progress the team has made, challenges overcome, and includes footage of a few of the first stable, controlled flights of the third generation of this two foot, one pound aircraft. NASA Armstrong Chief Scientist and Prandtl-m Designer Al Bowers narrates.
