    Lippisch DM-1 airworthy faithful replica...

    At Langley full size wind tunnel, they show for DM-1/ Lippiesch L-13 (The 'Sagitta' of Airbus) a traditional bubble canopy, a vertical fin, plus a thin vertical rudder improved results, also having an extra in leading edge. Blessings +

    Very low aspect ratio planes?

    You for sure have the Langley Lippisch L-13/ DM-1 wind tunnel study, but some may like having it here. The image of so called 'Spinning top' 'Peonza' looks rather a concrete building than a flying machine. German flying disc images look most counterfaited, the Schriever's machine is impossible...

    Very low aspect ratio planes?

    This is my proposal for an improved Bumble Bee, a triplane, more wing area, as for having a decent landing, takeoff and stall speed, still kept wtithin the 249 cm limit to land or drive in roads. Blessings +

    Very low aspect ratio planes?

    The Jules Verne 'Master of the World' flying machine was described with an arrangement a bit as in the attached image, but I forgot what is this. Blessings +

    Very low aspect ratio planes?

    You may like the shape of the Airship in attached image, a design, from early in 20th century, by Spanish Artillery Officer Manuel Rivera y Sempere. Handwritten original, 'Sistema de navegacion aerea', is available in CD-ROM from 'Patrimonio Nacional' Blessings +

    Very low aspect ratio planes?

    Nice document. Is this the so called 'Rogallo Wing'? Some had fatal accidents after a dive, when the air blow keeping the 'airfoil' shape and wing working reversed, and lift was no longer provided. The document deserves some work in 'Microsoft Office Picture Manager', or other image editing...

    Very low aspect ratio planes?

    Dynafan is a 'Coanda effect' machine, lots of it appear in YouTube. Valeriu Dragan, at Bucharest University, published some engineering research about the Coanda concepts. Blessings +

    Very low aspect ratio planes?

    As I don't remeber if I added the document: 'Characteristics of Clark Y airfoils of small aspect ratios', NACA report 431. C H Zimmermann. I attach it now. The interesting info is an AR of 1 gives impressive better results compared to an AR of 2 or 3. Blessings +

    Very low aspect ratio planes?

    With 3500 mm span, it's still above the upper limit on road, 2490 mm, again, a triplane Bumble Bee may perhaps meet the requirement. Blsessings +

    Very low aspect ratio planes?

    Soviets always in 'Gay is cooperative' zone: Beatles' 'Yellow Submarine' animation movie is also Gay a flying disc, close to the German antecessor, was built, 2nd Russian video, the 'Mint little bird' style, in Australia. Lippisch DM-1 data from Langley full size wind tunnel are available in...

    Very low aspect ratio planes?

    Hi!: I'd say Bumble Bee could have a decent take-off, landing and stall speed, still within width limits for cars and motorcycles on the road, speed limits on ordinary roads, by making it a triplane, instead of biplane. A high dihedral wingtip box including all three wings could improve all...

    Spark redundancy.

    You know the Series A Citroen cars: 2CV; Ami; Dyane; Mehari, had a twin flat, last of 602 or 652 cc, air and oil cooled engine, with no distributor, an spark lost every cycle. Savoiacars.com in Argentina proposed avionized versions of it. Blessings +

    Mazda Rotary Engine

    You already have the Aixro, the Wankel Supertech, the AIE.uk, the Austro. If Mazda produces the well expected Wankel RCE Powered Range Extender, no guarantee they will sale it to everybody, D-Motor in Belgium refused selling their side valve engines to homebuilders, just to regular makers...

    "Beast One" - the next generation Microjet

    Two ideas already consulted elsewhere: a MiG-17 with an Area Ruled fuselage?, an F-104 with an straight leading edge wing? Would this improve somehow these aircraft? Blessings +
