I think I've seen more interesting and unique designs in this one thread alone than I have in years. I knew about the Spratt Controlwing - not so much about most of the others.

Thanks, Qxev!

please


I am glad to be to you useful

 

[qxev]

I am curious what you opinion is, but I am having a hard time understanding.

Can you just spell it out? Maybe someone can translate this into simple terms so that I can see what you are after. You seem to be onto something, but I don't see it.

Holden

Holden you think, what the most important is to construct the good flying device (which it will be better than Cessna)?

it also - the main mistake of all designers...


the main problem - not to construct very good flying device...


and that this device was started in the sky (allowed its mass use officially)...


without creating artificial obstacles (in interests of a lobby of the leading companies of aircraft)

try to understand...


whatever good airplane you made...


nobody will allow to use it - if it causes a financial damage to leaders of the market

 

[qxev]

I will give some examples

CBY-3 called so from names of three partners, participating in its creation: Cancar, Burnelli and Lowell Yerex and "3" on number of partners was спроектирван specially for operation in bad airfields with short VPP. therefore had very powerful chassis borrowed from a heavy bomber

Besides the bearing case, characteristic of a design – existence of a power framework of safety of passenger salon, as in racing cars

 Burnelli CBY3 Loadmaster

it is extremely good plane... high safety from accidents and fires...


and it is completely tested in the sky and on the earth

Pilot отчет: Этот очень стабильной и прочной, компактной фюзеляж огромного объема вызывал чувство защищенности как в бронированном автомобиле, летные характеристики были превосходными..
. при выходе из строя одного двигателя проблемы асимметричности тяги были практически нулевыми, и в стабильности практически идеальный по всем осям.
Выполнял любые эволюции, но стоило выпустить штурвал, как самолет переходил в прямолинейный полет

.На жаре днем в Майами, с 9000 фунтов перегрузки, самолет отрывался от земли с разбегом 1400 футов, вылезая в небо с фантастическим углом.

С аналогичной нагрузкой, C-46 потребуется разбег около 3000 футов.

После опыта своих полетов на CBY-3, и признавая его уникальные средства обеспечения безопасности, я не мог не думать: «Какого черта мы все были вынуждены летать в этих опасных обычных самолетах все эти годы? (- Чалмерс Goodlin, 1998 один из самых знаменитых летчиков-испытателей)
Burnelli

Эта машина прошла тщательное тестирование и показательные рейсы , чтобы продемонстрировать свой потенциал. Несмотря на бесперебойную программу испытаний и блестящие отзывы прессы и отраслевых наблюдателей, производственных заказов не поступило

..хотя LoadMaster мог нести нагрузку в 3000 кг и имел сиденья для 24 пассажиров, он получил лишь ограниченный внутренний сертификат летной годности…
В феврале 1951 года, CC & F отказался от попыток получить LoadMaster полную сертифицикацию в Канаде

the super good airplane - permissions to use simply didn't give

it simply burned with the criminal way cleaned from the market...

in this regard I have a question to Holden :

why you think, what by the plane the market someone will allow you (with your newSea-Era )?

You are a son-in-law of the American president?

 

[Holden]

qxev,

No, I am not son-in-law of Obama. Romney's son did a housing subdivision next to my house and I met his youngest son.

I guess you think making a good airplane will be quashed by "them" and the bankers. You may be right. At least I will have what I want.

Sounds like you have to have connections in Russia to do anything. Getting more so in the USA.

But, I am curious, what do YOU think would be good. You show all these airplanes, but don't really state what you think is the way to go. Hovercraft?

I try to direct your thought on the MAIN problem


1) in what market it is possible to start NEW type of flying devices?


2) what requirements are put forward by this market?
obviously, such market is poor countries of Africa. Asia. Oceania.


and most important requirement of this market:
1) that any monkey who слезла from a palm tree - could operate yesterday the new flying device quietly
2) that this device had cost of a second-hand of ordinary airplanes

we see the eyes that on Hoverving any monkey is capable to fly...


it is logical to alter this Hoverving so that it could fly at big height....


and to put there the cheap automobile engine, for depreciation of the new flying device

Holden

I "think" nothing..., and simply I see the world as it is in reality

At least I will have what I want.

for the sake of sports pleasure it is not necessary such efforts, as development of new types of flying devices....


any designer hopes that his creation will serve many people

but it is initially necessary to use infallible LOGIC


1) aircraft of new types - never will manage to be lifted in the sky of the developed rich countries (if only you not the Boeing... Rothschild... or Obama)


2) the market of the poor countries dictates the MAIN requirement to new flying equipment - "super availability of using"


here proceeding from these axioms of life - it is necessary to begin search of a design of the flying device

 

[qxev]

the section "engine" deserves especially careful attention.


as the most suitable I consider rotor and piston engines Mazda...


which are used for a long time by planes, and have a set of accessories

From the moment of start by our first line of products, the AE50R series, ours of 50 horsepowers the engine a successful track record, from more than 700 installations in the engine of gliders and helicopters of the chamber of leading OEM manufacturing. Our rotor engines small, easy also have vibrations standing out low level. Their reliability and adaptability allowed to develop more, more strongly, the rotor engine, AE75R which will be available soon.http://www.austroengine.at/cms/front_content.php?idart=37




Diamond Engines are offered already by two engines, both are based on Vankel's principle. It is less, Vankel's one disk, the IAE50R version from 294 cubic cm and combined liquid and air cooling makes 55 h.p. (40,4 kW) at 7750 turns, at a sea level. The engine works for aviation gasoline (100LL) or MOGAS (ROZ95 lead). Diamond Vankelya, also one engine of a disk is more, extracts of 75 h.p. (55 kW) at 7500 RPM from 404 cubic cm also uses the same fuels.

A good friend of mine, Ben Schneider, is installing this package in his RV-7 just down the road from me. Honestly, he is the one that turned me on to the rotary before I started building. This is a do-it-yourself systems build, so engine skills and knowledge of the rotary engine is a MUST to go this route. RWS makes the redrive, and there are various options for props out there. There are a bunch of these flying, and the bugs are being worked out. Tracy Crook is the mastermind behind this installation, and he knows what he is doing. This is probably one of the best budget buys for an engine out there with complete firewall forward packages coming in WELL under $20k. Runs on 100LL or unleaded and cheap overhauls.

qxev,

As I stated on roadable airplane design thread this is what I think would work. http://www.homebuiltairplanes.com/forums/aircraft-design-aerodynamics-new-technology/11987-roadable-aircraft-design-41.html#post154113

That is, namely, a $25,000 pod that can be used on a daily basis to take kids to school, grocery store. The wing is removed and the wing has an engine it it up front. The pod has an engine in it that has a transmission (Motorcycle engine, suzuki 650, for example). That engine drives a small prop and the rear wheel. The pod can run on water or snow and road without the wing and the "airplane" engine up front.

The controls are like a motorcycle with throttle in right hand for rear engine and left hand for front engine. Rudder pedals steer the training wheels, and the handle bar steers the front wheel just like a motorcycle does.

Pod can get 100 mpg fuel economy because it is 1/4 the weight and drag of a Buick which gets 25 mpg. People buy the pod without the wing because it is MORE fun than a car and has 4 times the fuel economy for the same number of kids. Most cars do not allow a child to sit in the front seat because of the airbag and therefore can only hold 3 in back. The pod can hold 5 children and one adult up front. This is what a minivan can do.

The pod can drive flat like a car, counter-steer like a motorcycle, or use the training wheels and bank like an airplane. This way a person then learns how to "fly" on the ground by using bank angle to steer, yet can still use flat or counter-steering in heavy traffic until they learn to fly on the ground. Later when they get money they buy the wing with the airplane engine for $25,000. Total set up $50,000. Since they use it daily and the "fly" on the ground, it becomes second nature.

If they want to go flying they install the wing (10 minutes), and they drive to an airport of farmer's field or to a gasoline station for fuel in the wing for a long trip. They bank it like an airplane on the road which best deals with the high weight of the wing and engine. During the trip the engine warms up the coolant of the airplane engine so that it is warm and ready for take off. They start the airplane engine and warm it up depending on where they are. Wing swings back, pull onto runway and off in 100 feet. The two engine then back each other up. If one fails, they land and drive. The engines are cheap because you can land on a road rather well if need be, and if one fails you land.

I think this would sell 100,000 Pods/year or more and maybe 5,000 wings/year. Now you have volume. Costs met.

That is what I think will work.

What do you think?

Qvex,

Comparison:

Option 1:
$70,000 airplane,
$20,000 floats
$30,000 minivan/car,
$20,000 boat,
$10,000 (min) Pick-up truck to tow boat.
Total capital: $150,000
Four insurance policies, hangar rent, annuals, storage, parking space for three vehicles at home, no way to get to destination, need pick-up truck to pull boat to lake, more time in travel, not easy to use because of time and lack of access to remote places. Not a pretty cost situation…

Option 2:
$25,000 pod that can function as a boat
$25,000 airplane engine and wing that can land on water.
Total $50,000
Don’t need: boat, Pick-up truck, hangar, three more insurance policies, space at home for three vehicles, taxi from airport to final destination….
A complete analysis would shock you and take a lot of space (best for another time).

Which do you think would be best?

I would say Option 2 is 3-4 times better, if not 10 times if you are into business and have to travel around where there are no airports close by.

This pod airplane (option 2) would get people into aviation.

With Option 1 the airplane is left out in favor of the boat and pick-up truck due to cost to benefit.

Aviation competes with boat and loses. This is the status quo.

The old Sea-Era was just a little better than Option 1.

The new design is a much better vision and value and can fit within a middle class income. Option 1 is out of reach of most people by 3 times.

How do you see it?

Holden

 

[qxev]

I will give my arguments a little later

 

[Holden]

=summary =very promissing principe!

-pardon=many aspects are cleared at=Roadable Aircraft DESIGN

The Sea-Era delta part would be on top instead of on the bottom. Some parts of the Sea-Era bottom will remain on the bottom for water interface, along with a ski so that the hull will not sink it if it hit a rock. The rear prop is 4 ft and is below the upper wing so that flow is not disturbed by long delta wing chord. Delta wing (center part) has a tractor engine up on the tip of the delta. The front pilot sits on the front tire, second row is on CG, and third row is aft, just forward of the rear engine. Most is plexiglass and not "composite" that cannot be seen out of. I am still looking at several ways to do the rear prop so that the flow into the rear prop is excellent. Remember, the rear prop is for backup in case the front engine quits and boundary layer sucking and it runs only at 30 hp during cruise so that an off the shelf engine can be used ($2500). It can run at 65 hp to get you safely on the ground if the front engine quits and it helps on takeoff a lot and allows high power high drag landing with the front engine.

The point is that the basic configuration gives the needed safety, roadability, power on landing over the large delta with large flaps, and the landing gear allows it to land where no other airplane can. This is what I want, just need to get it into a good looking design, which is not easy.

1) how many money it will be necessary to enclose, on Crash Test that the administration officially allowed transportation of children on this device?
(at a rate of similar expenses of automobile concerns as Ford... or it is even more)

2) what will be device weight taking into account providing the necessary degree of durability of a design.... at level safe Crash Test of collision of cars on the highway?

(weight it will be much bigger, than at a usual design of the plane of which don't give durability to bear blow of the counter car on the highway)

3) what laws authorize operation of such device (the car + the airplane rolled into one)


4) how many money and time is required for creation of such laws (a lobby in the senate. and other)?

5) how many money is required on expansion of a network of services for service "the car + the plane"?


6) how many money is required for creation of schools of training on "the car + the plane"?

conclusion:

idea the in itself interesting... but its embodiment will need enormous expenses of money and efforts...

with very ambiguous result...

besides, to explain thought to people - it is necessary to show, at least, the most primitive drawing (image) your option "the plane car"

I expect the main obstacle in combining quality "durability from blow" (an automobile standard) with quality "an easy design" (the airplane a standard)

I believe that it is possible only on the basis of high technologies and expensive materials... that will demand very considerable financial expenses
