Red Jensen - Formula 1 "Impulse"
Red Jensen describes the design and construction of his upcoming Formula 1 race place, "Impulse." Dr. Al Bowers provides the introduction. The aircraft is all carbon-fiber composites, with Nomex honeycomb used as a core in the fuselage shells. Resin infusion is used cleverly here in part of the process.
NOTE: I have deliberately darkened the video and increased the contrast in order to help enhance the visibility of the projected images. The room was pretty bright. Due to our normal videographer being unavailable, the video was shot on a cell phone. The automatic exposure adjustment of the cell phone camera is made more visible by the darkening and contrast adjustments, and this is why the video seems to darken and lighten at points during the presentation.

"World's Cheapest Electric Airplane/World's Priciest Flying Gamble" - Dean Sigler
มุมมอง 5255 ปีที่แล้ว
Dean Sigler, author of the 'Sustainable Skies' blog on electric and hybrid aircraft (sustainableaviation.org) discusses his current "cheapest electric airplane" project, and then gives an overview of the current crop of electric VTOL "air taxi" concepts on the drawing boards of Airbus, Boeing, and others. Various concepts and challenges of the VTOL air-taxi model are discussed. Recorded at the ...
"Testing Flight-Test Instrumentation (Without the $30,000 Toilet Seat)" - Andrew Angellotti
มุมมอง 4565 ปีที่แล้ว
Flight-test instrumentation is a critical part of validating design goals, but how do you know your instrumentation is reading correctly? "Conventional" validation and calibration methods can be horrifically expensive and time-consuming. Andrew Angellotti shares how his company, Spingarage (www.spingarage.com/), uses unconventional and creative ways to validate and calibrate instrumentation ver...

"Caro 1 Motorglider" - Sonja Englert
มุมมอง 1.6K6 ปีที่แล้ว
Sonja Englert gave a presentation at the 2018 ESA Workshop in Tehachapi, CA, about the design, construction and testing of her motorglider. Caro 1 is an all-composite tandem-seater which was built by her in her garage. In order to realize its unique shape and keep it light-weight, simple, inexpensive molds were made for the airframe. It is powered by a 4-stroke engine and has flown about 200 h ...

"Application of Lifting Line Theory to Wings with Sweep and Dihedral" - Don Crawford
มุมมอง 1.9K6 ปีที่แล้ว
A presentation at the 2018 ESA Western Workshop. Lifting line theory is applied to a smooth bound vortex with sweep and dihedral and a trailing vortex sheet. The circulation function on the bound vortex is expanded in a Fourier Sine series with coefficients determined by conditions of total lift and continuity of the vertical velocity and slope at the wingtips. Changing the value of Prandtl's w...
"Configuration Aerodynamics - Classical Methods Applied" - J. Philip Barnes
มุมมอง 8786 ปีที่แล้ว
A presentation at the 2018 ESA Western Workshop. This presentation, by J. Philip Barnes, Senior Technical Fellow at Pelican Aero Group, renews basic principles of subsonic and transonic aerodynamics with application of an empirical lifting line to compute the distribution of lift, and the author's "apparent upwash" method to evaluate drag due to lift. The author's EXCEL models for airfoil and v...
"Autonomous Dynamic Soaring Cargo Motorglider Concept" - Richard Starke
มุมมอง 4.4K6 ปีที่แล้ว
The bulk of shipping tonnage is in the Northern Hemisphere; between China, US and Europe. In order to reduce CO2 emissions of air freight per lbs-mile, a conceptual operation and design of an autonomous dynamic soaring cargo motorglider using the jet stream is discussed.

"Prandtl Wing Minimum Drag Update" - Al Bowers
มุมมอง 34K6 ปีที่แล้ว
A presentation at the 2018 ESA Western Workshop. For nearly a century Ludwig Prandtl’s lifting-line theory initially points to the elliptical spanload as the most efficient wing choice, and it has become the standard in aviation. Research in bird flight has increasingly generated data in disagreement with the elliptical spanload. In 1933 Prandtl published a little-known paper presenting a super...
"Ultralight Sailplanes" - Dan Armstrong
มุมมอง 5K6 ปีที่แล้ว
A presentation at the 2018 ESA Western Workshop. This talk is based on Dan Armstrong's personal experiences in hang gliding and ultralight gliders and is intended to show some of the history of ultralight gliders, some practical aspects of their construction and operation and why they remain a real possibility for the future. Several questions from the audience are answered at the end of the ta...
