    Rutan Boomerang Variant

    Ahoy, All, My offering today is a Boomerang based airplane. This Rutan design has MUCH to offer in terms of performance and efficiency. Third-hand observations suggest that the need for re-trimming is a PITA, but I suggest that modern methods and/or autopilots can eliminate that problem...

    New Design Configuration

    Ahoy, DaveK, Interesting idea which may have significant merit. I don't know how powerful CFD is, but one would certainly need to refine/prove the configuration with a wind tunnel model. The occupants and fuel can be located such as to balance the entire scheme. Perhaps someone with...

    New Design Configuration

    Ahoy, Bill, The paragraph toward the bottom of my text lays out pretty much the only possible way to success: A group of (well funded) airplane enthusiast investors who want a fast sport plane and a chance to make some money. (There have been a lot of these same sort who have fallen by the...

    New Design Configuration

    A number of questions. #1 Plenty of tail volume. #2 For CFD and FEA engineers. #3: Bail-out is a hatch in the floor. #4 I doubt if it can recover from a spin. Big spin chute (plus pilot chute) for test? #5 Big fillet. #6 Nothin' is perfect. Thanks for your welcome remarks/questions...

    New Design Configuration

    Ahoy, Brunner, This text, (which was attached in the original post, but will not open) pretty well explains the advantages. I have a serious quarrel with this present web site. No longer any ability to preview post, and in general too hard to use. Enjoy /s/ Bob

    New Design Configuration

    10-10-23 Ahoy, Homebuilders, Homebuilt Aircraft & Kit Plane Forum -- see forum: Aircraft Design … My objective is to induce some interest in a new configuration twin engine four place sport plane. In order to keep it easy to handle and build, matched hole aluminum, center-line...

    Bob Belter Airplane design

    Ahoy, Homebuilders, Homebuilt Aircraft & Kit Plane Forum I have a very detailed revelation of my airplane design, no longer a B 82-E twin Mustang style, but a tractor fuselage mounted engine, with a second tractor engine, pylon mounted, which is my ‘winner’, along with .DWG files which you can...

    Twin engine f-82 style

    At 94 years, my only ‘elder’ entertainment remains airplane configuration design. I was the Navair Design Officer of the A6E Intruder, and that did not turn out too bad, with more than 500 built. My present interest is in two airplanes: First is a fast personal two or four place twin engine...

    Twin engine f-82 style

    Ahoy, Homebuilders, I have an airplane design which follows the North American F-82 style, with two Aeromomentum engines. My write-up and .DWG drawings are far too elaborate to simply post, so I need some advice on an appropriate next step. A Merry Christmas day to ALL. /s/ Bob --Robert...

    New airplane design

    Ahoy, Kitplanes, I have a new twin engine airplane design, but it is way too elaborate to simply post it. I have spent a lot of time trying to find out how to contact Mark Cook, to no avail. I need some advice on 'what-next'? Enjoy /s/ Bob Belter Carmel CA EAA 8444

    Aeroelasticity

    Ahoy, All of you airplane builders, The title notes aeroelasticity, but it is that of a swept wing twin jet (A3 skywarrior) of 60+ years ago. This is so far away from present day homebuilt airplanes that I ask if any of you want to take a look at it? If so, please note any interest in the...

    Modern jet Airplane drag

    10/11/2022 Ahoy, all of you modern Aero Engineers. ( I are-wun, but near to 60 years out of date). (I was the NavAir Design Officer of the A6-E intruder. It turned out OK, with about 500 built). My query is: Please define/explain the aerodynamic drag of the ‘scrotum’ under the wing/fuselage...

    PDF of Aeromomentum AM1.5T and AM 20T

    Ahoy, Aeromomentum, I did ask on 14 September 2022. ‘Ahoy, Mark, I like your ‘style’, and your engines. At 94 years, my entertainment is doing three view drawings of 2 D airplane designs. I never have become comfortable with these ‘proper’ 3D programs. I fortunately retain my spatial...

    PDF of Aeromomentum AM1.5T and AM 20T

    Ahoy, All, I am not able to find three view PDF's of the subject engines, to 'rough-in' a design using either. ( I do have an earlier PDF of the slant AM 1.5 engine). Does anyone have such? Thanks /s/ Bob Belter EAA 8444 [email protected]

    High compression at altitude

    7/17/2022 Ahoy, Homebuilt Aircraft & Kit Plane Forum, below you will find a dialogue between myself, and the smartest engineer who I have ever known. (Name redacted). He is the gifted designer of airplane engines, PSRU’s, and a lot of other projects. Please read my bottom discussion first. He...
