Wait till you see the bigger versions, such as the liquid propane/natural gas tankers.

JESUS ! BIGGER ?!

is this a "Wing In Ground effect" craft or is this a high altitude Aircraft ?!

High altitude. The Model 759-127 was the largest that I have data immediately to hand on... span 515 feet, payload 1,815,000 pounds of LNG. Other designs had payloads of LNG of over 2 Mlbs.

joncarrfarrelly · 2 April 2009

I swear I saw the plans for that in an old Flying Models under the control-line stunt category.

mz · 2 April 2009

Notice the front end and cockpit stays the same as earlier Boeing models so type certification of pilots is easy!

Hi,

it seemed to be there was a competition for Spanloader aircraft.

Hi,

here is anther Boeing configuration,with only four engines and folding
wings.

Finally here it is, when I was a kid (back in the 70's) it was taken for granted that in future the spanloader would replace airliners.....

Sentinel Chicken · 7 March 2010

Damn, that's nucking futs! An airborne fuel transport? 2 Mlbs is one helluva an FAE.......

Are you referring to the Boeing Resource Carrier 1 aka "Brute Lifter"?

...An airborne fuel transport?

Don't know if anyone's seen this, from Air International,
June 1979..........

Technical and Economic Assessment of Swept-Wing Span-Distributed Load Concepts for Civil and Military Air Cargo Transport, Preliminary Design Department, Boeing Commercial Airplane Company, October 1977

Abstract:

A preliminary design study to assess the technical and economic feasibility of large sweptwing span-distributed load freighter aircraft to be certified in 1995 has been made. The study also assessed the impact 'of military requirements on the performance, economics, and fuel consumption characteristics.

The study was limited to configurations having net payloads of 272 155 to 544 311 kilograms (600 000 to 1.2 million pounds) contained within swept wings of constant chord.

These configurations are of advanced composite construction with controllable winglets and full-span digitally-controlled trailing-edge surfaces. Civil, military, and joint civil/military production programs were considered.

Hi,

here is a Model for Boeing Spanloader aircraft.

In the 1970s, Boeing studied the concept of a "distributed load freighter," a six-engined giant designed to carry containerized freight at a much lower cost per pound then was possible at the time. In the concept pictured here, the payload would be carried in two pods, one on each wing, each 26 feet in diameter and 150 feet long. The pods could be removed and replaced, whether empty or full, within minutes, and could be used to carry almost anything. Because of its landing gear width, it would operate only from airfields dedicated to air freight.

Great find my dear Rolf.

No info on this passenger design. BOMAC = Boeing McDonnell? 900 = model number? Feel free to move if this is not the correct spot for this.

hesham · 7 March 2015

Great find RAP,

but we get confuse,the Boeing Model-900 was a proposal for Tri-Service contest;

Hello Hesham,

The link is down. I was wondering if you remembered the name of this report or still had the pdf?

I'm trying to research the flight control system and g-limits of the Boeing 759 studies.

hesham · 15 February 2017

The link is not down,

and I have it if you want,send to me your E-mail in private message.

Avimimus · 15 February 2017

Thanks to our dear Hesham - Here are some excerpts I've made on the proposed control systems for the tailless versions (From Paper 78-100 at AIAA 16th Aerospace Sciences Meeting, Huntsville, Ala., Jan. 16-18 1978):

"The figure shows the strong influence of airload distribution on bending moment and the importance of the tip fins in producing an efficient spanwise airload distribution. The simple rectangular planform that houses the payload is not nearly as efficient as a more tailored planform in producing the elliptical Joad distribution. The tip fins carry the required lift to increase effective aspect ratio from 4.9 to 7.9. This results in significant improvements in LID without a significant penalty on wing bending moment. [...] Whereas normal airplane configurations with tapered wings require considerable twist to prevent tip stall, the rectangular wings on distributed load airplanes will have lower section lift coefficients at the tip. Therefore it is possible to build the basic wing box without twist and to control the span load distribution with relatively small deflections of the control surfaces."

"An essential function of flight controls will be to regulate flight loads at all times and, as such, the controls will become as important to the airplane as the primary structure itself. [...section on multiple redundant computers and automated-diagnosing of system failures]"

"The control surfaces function both as flaps and primary flight controls. The wingtip fins provide directional and engine-out control. Operated together, they function as both a redundant pitch control and as side force generators. The airplane with this system is capable of direct lift control, permitting a flat landing attitude. The large span makes it desirable to land at very small roll angles, and it is probable that a tight control on roll will be maintained automatically during landings."

"The control surfaces function both as flaps and primary flight controls. The wingtip fins provide directional and engine-out control. Operated together, they function as both a redundant pitch control and as side force generators. The airplane with this system is capable of direct lift control, permitting a flat landing attitude."

My dears Gabriel and Retrofit,

Unfortunately I can reach to it in my files now,but I will search about it.
