DARPA Lift Challenges: Goal-Driven Innovation Beyond the First Prototype
Hot on the heels of today's DARPA announcement of Lift Challenge 2.0 (yes, they're officially doing another one, which we suggested they do in our recent article), this week's Inside Electronics episode has guest host and Electronic Design Technology Editor Andy Turudic sitting down with DARPA’s Lift Challenge Program Manager, Philip “Donna” Smith, and Science and Engineering Technical Advisor SETA) for DARPA's Tactical Technology Office, Ed Marin. We unpacked the dramatic innovation that was motivated by the recently wrapped up DARPA Lift Challenge 1.0.
Designed to break records in economic and operational payload-to-weight barriers for vertical lift aviation, the high-stakes competition offered $6.5M in prizes. It challenged teams to design lightweight aircraft capable of lifting payloads of over 4X their unladen weight (watch the video version of this podcast, expected later this week, to catch high-resolution flight footage and breakdown diagrams of the competing aircraft).
Smith and Marin share how they took the program from uncovering "customer" problems, gaining executive approval, and successfully managing a challenge program with execution in just 11 months. The DARPA Lift Challenge (1.0) set up a demanding 1,100-ft. course at the National Museum of the U.S. Air Force. The flyoff week had close to 300 staff and volunteers, to push small-scale, heavy-lift innovation to its absolute limits.
We break down the highs and the lows of the competition and uncover exclusive, behind-the-scenes facts, analyses, and commentary that won't be found elsewhere in a fun, engineers-having-a-beer, discussion style.
If you want to learn how to seed and nurture innovation in your organization from product concept all the way through debug and fault-finding on a short timeline, this podcast is a worthwhile listen.
Unscripted, unplugged, and no question or comment off limits, you'll be listening to engineers and program managers talking the language you want to hear. We also covered a topic that was unspeakable last week: "What's next?". We recorded it under mutual agreement not to disclose the content until today's DARPA announcement — there will be a second DARPA Lift Challenge (see Andy's article).
We wanted to get last week's Zoom call out for our readers to have a listen in time to help digest today's announcement. We're going to have very unique, super-detailed video on the Lift Challenge 1.0, with video content from The Challenge, that meshes perfectly with the analysis in the audio, coming out in a few days.

About the Author
Andy Turudic
Technology Editor, Electronic Design
Andy Turudic is a Technology Editor for Electronic Design Magazine, primarily covering Analog and Mixed-Signal circuits and devices and also is Editor of ED's bi-weekly Automotive Electronics newsletter.
He holds a Bachelor's in EE from the University of Windsor (Ontario Canada) and has been involved in electronics, semiconductors, and gearhead stuff, for a bit over a half century. Andy also enjoys teaching his engineerlings at Portland Community College as a part-time professor in their EET program.
"AndyT" brings his multidisciplinary engineering experience from companies that include National Semiconductor (now Texas Instruments), Altera (Intel), Agere, Zarlink, TriQuint,(now Qorvo), SW Bell (managing a research team at Bellcore, Bell Labs and Rockwell Science Center), Bell-Northern Research, and Northern Telecom.
After hours, when he's not working on the latest invention to add to his portfolio of 16 issued US patents, or on his DARPA Challenge drone entry, he's lending advice and experience to the electric vehicle conversion community from his mountain lair in the Pacific Northwet[sic].
AndyT's engineering blog, "Nonlinearities," publishes the 1st and 3rd Tuesday of each month. Andy's OpEd may appear at other times, with fair warning given by the Vu meter pic. His cartoon series, "Inventors", appears each week in Electronic Design Weekly.
