Two stroke engines in a racer ?

[First time Juke]

Baby

Yes !

We have a daughter 15½ months old by now. She is pretty interesting..climbing a lot and running like a race horse around the house. She can be very loud at times too. Likes to bathe in sauna a lot.
I'd like to train her to be a great golfer but she is too young to grab the club with two hands. Have to wait till Kidz USA clubs are right size ( next summer ). She is about same age as Tiger Woods' daughter Sam.

rgds,

Juke

PS: Can you tell where I was as exchange student by her sweather ?

Re: Two stroke engines in a racer ?

I always wondered how you got introduced to our crazy part of the world!

She looks like a really happy baby!!

Wayne,

Intoduced....well we are crazy ok...see the RED BULL flying day in Helsinki ( video );

flying wing is pretty cool...at the end.

Re: Two stroke engines in a racer ?

Sorry Wayne,

I was really tired at evening...I totally missed the message...you referred to the sweater. I recall Finland has been labelled as the most americanized land in Europe. Because we see all films undubbed maybe..or because there are 600 000 finns in USA....over 10% of the population ( in Finland 5.3 mio nowadays ).
Duluth is possibly most finnish city in USA...never been there though..but I certainly recommend Newport R.I...it is smallest state, but has lotsa beaches, water, lobsters and good stores etc. and very friendly people.
I was also putting up tents with Newport Tent Company around New England...greetings to Mike if he reads this ( possibly not ). Also the Americas Cup Races were held in 1980 there as I was there. Town was also loaded with heritage..huge mansions like the Breakers etc. but mostly smaller colonial style houses..with ordinary hard working honest people..whom I miss time to time.

rgds,

No money for Tweedy-Bird ?

I got negative answer when I applied for a state fund for Tweedy.
I think I have to bury also this project for now since it has been time consuming and response has been nonunderstanding. No use trying forward.

I have to concentrate on my "real" job; being an architect.

Thanks for everyone for their interest. I am really in awe; what is more important than a family AC that uses less gas than a car and gets you there in half the time and is less expensive to manufacture by far ?

Re: Two stroke ( or four stroke ) engines in a familyracer ?

Here is more updated version of this GELB ( Ground Effect / Lifting Body ) project whose aim is to make really ecomical flight possible.

85 mpg is not just a dream but based on a realistic educated guess ! : )

Re: model and proto to be single engine type

Due to lack of interest I desided to go for a single engine version with same economical ( gelb ) princible.

Plane will be studied first with a model and possibly a under 70 kilogram ultralite ( 3 FAI records in mind in that category ).

Making it under 70 kilos ( emptyweight ) will help a great deal since that kinda plane needs no certification nor lisence to fly it.


CS-VLA requirements in Europe can be found here;

http://www.easa.europa.eu/ws_prod/g/rg_certspecs.php#CS-VLA

( VLA = very light aircraft => mtow under 750 kg )

----------------------------------

2 seater ultralite should be under 450 kg and one seater 300 kg ( flyweight ).

----------------------------------

The intented goal of setting 3 FAI records in ultralite category would serve the purpose of getting a kickstart to the marketing of the AC. If it falls out of the ultra class then I try the distance and speed records under 300 kg category of FAI records ( these are tough to beat ).

Yesterday I made hand drawn scetches for the shock abrorbed tailskids to be used in the twin tail along with the extremely light retractable nonturning mainwheel. Skids will turn along the rudders to provide directional control under taxiing and take-off ( + landing ). Extremely small tailwheels could be used too ( 3 cm diameter ).

Plane sports also very small sweep in the wings and possibly an open cockpit or cosmic wind canopy ( + opening off sufficient part of the upper tail fuselage with it in order to bail out in emergency ).

Can anyone comment when does one need vortilons in a swept wing AC ? I see all new Vari-Ezes do need them installed.

Main reason to do these changes now where to cut down intersection drag and weight. Keep it clean as a whistle as a main goal.

Re: Two stroke engines in a racer ?

I will continue to use the one wheel main and two tailwheels.

I tought this was very original, but then I found these;

Aria ( 64 hp ):

X-15 ( mach 6.7 ):

http://www.youtube.com/watch?v=Ueqml_sYDFU&eurl=http://www.ilmailu.org/forum/index.php?topic=536.100

at 20 second pace the landing...see the skids and mainwheel !

Re: Two stroke engines in a racer ?

I have readied now also 2 x 50 hp version ( along with the single engine craft and 2x22 hp version ).

This could brake the under 300 kg FAI record by far.

Tweak those 50 hp engines a little ( that only weigh 16 kilos each ) and you have 400 mph+ mover. 5 blader small props are needed too.


50 hp 16 kilo Limbach L550E engine:

Re: Racer update !

Ok ladies and gents !


Here is the racer version of Tweedy Bird 3 seater; P H O E N I X II.

( I had a small uniwheel R/C model that I named Phoenix..thence the II )


On paper this should brake 218.3 mph speed set with Bede-5B.

Propelled with tuned Limbach L550E engines and 4 blade fanpropellers.

Power to weight ratio better than in wartime P-51D Mustang.

This must have flaperons to work ( unlike drawn in the pic ).


...and what colour would you like your racer to be ?

Will we have a new racer class now ? I wonder if mr. Burt Rutan ( of Scaled Composites ) would be interested to make this what it could be ?

Re: Two stroke engines in a racer ?

This could have fully retracting main landing gear in Tweedy style.

This is a plane that aim is to be under 70 kilos with 12 l of fuel.

Engine could be from DA-170 to L275E ( and APT 200 cc ).

I have CAD drawn R/C model plans almost ready now.

Here is the ( GELB technology ) MAX II

[First time Juke]

Re: Two stroke engines in a racer ?

I have done an updated and more efficient MAX that I call now MINIMAX.

It is 12 ft long and spans some 18 ft.

It has radically more simple tail and lighter..a lot lighter..I'd say it weighs now under 50 kilos ( 110 lbs ) empty, but it would still be moderatly aerobatic.

I have also managed to enlarge the main wheel into 2 feet dia so it will cause very little friction at take off. Tail wheels ( dia 9 cm ) are also now in tact like in Aria ( the unfinished record braker..link previous page ).

I assure you there is no AC with less induced drag than in this one. The ground effect is in much more effective use and the body lifts like a bird. Only a flying wing could have less intereference drag than this ( but I doubt it when engined, ruddered and wheeled ).

------

God, I wish I had a workshop ( and an aerodynmist friend + mio.usd to develop it into marketplace as a thoroughly tested product ).

A passenger plane sketch with this idea.

Shoud I just leave the wings off ?

Re: Two stroke engines in a racer ?

Ok since I promissed to invent an low cost racer and inspired by this pic:

http://www.nurflugel.com/Nurflugel/Horten_Nurflugels/ho_iv/Falvy_Pics/Img0076.jpg

I made another attempt to make world smallest twin..this time with unmatched speed as well so far.

God help me never to build it and fly it...but I just had to draw it.

The other on the right is the Minimax that I will try to make model first.

Still due to trade secret issue I will not show more than this. The pilot in Parrott single seater is in prone position for sure.


Happy Holidays folks !


PS: This would possibly be James Bond stuff or at least a competitor to to famous JETMAN of the swiss alps.
