Many years ago now I saw a broken Pacmin model of a Boeing 2707 300 in Airlift livery on Ebay. Recently I saw an Air New Zealand (not an optionholder) variant on Picclick.
It would be interesting to know from anyone with Pacmin connections if they kept records of the liveries made

https://www.fzt.haw-hamburg.de/pers/Scholz/dglr/hh/text_2007_04_11_RAeS_Concorde.pdf

From what I understand,
969-XXX were internal Boeing designations for some of the SST configurations.
Like the 733-XXX designations. Seems only when Boeing got awarded the contract did they assigned commercial Boeing 2707-XXX names, but Boeing 2707-300 still had 733-633 internal designation. the Boeing 2707 and 2707-100 and 200 were in the 733-4XX serie apparently, first one being 733-467.

Blackkite-San, please could you tell me what this means :


(or the all Japanese timeline text )
I’ve tried passing these into an OCR, then through a translator, but it gives me a gibberish about sea food and house construction… hardly SST related.

Late 1957

The technology developed in the WS-110A (B-70) bomber design competition and the core engineers in the design competition were gathered to form the first Boeing SST design team.

1960

In order to compare both the delta wing plan and the variable swept wing plan, Boeing created two competitive design teams in-house and conducted a competitive design. As a result of comparing the competition results, Boeing considered that the good low speed performance of the variable swept wing was very advantageous.

Mid 1963

NASA requested Boeing and Lockheed to conduct a comparative study on the four plans SCAT17, SCAT4, SCAT16, and SCAT15.

From early 1964 to mid-1964, Phase I

FAA requested each aircraft manufacturer in the US to propose a supersonic passenger aircraft. FAA selected the proposals of Boeing and Lockheed from the development proposals of each aircraft manufacturer and started the design competition for practical supersonic passenger aircraft.

Late 1964, Phase IIA

1965, Phase IIB

Early 1966, Phase IIC

Boeing reviewed and evaluated the delta wing aircraft with tails based on design proposal 733-204, but did not get much improvement and did not go deep.

Late 1966

Boeing won the SST design competition because the B2707-100 design proposal was advantageous at low speeds.

Late 1967 to early 1968, Phase III

Boeing decided to review the basic form of the SST because the B2707 series design proposal was stuck, and reexamined the variable swept wing plan, the delta wing plan, the SCAT15 plan.

Mid 1968

Boeing selected three proposals 969-302, 969-404B, and 969-320B that satisfy the requirements for payload, cruising range, safety, etc. after three months of study.

733-101

This is the first proposal for Boeing's variable swept wing SST. This plan was created based on research on TFX (F111) and arrow wings, which Boeing Co. and NASA conducted.

733-204

During Phase I, Boeing considered how far a good SST could be made using fixed delta wing. As a result of the examination, the proposal 733-204 satisfied the target value in the payload and cruising range, but the low speed performance did not satisfy the target value.

From 733-197 to 733-290

SCAT15F advanced aerodynamic design was used to improve from 733-197 to 733-290.

SCAT15F

NASA continued research on fixed arrow wings the SCAT15F proposal.

SCAT15F

Boeing reassessed NASA's SCAT15F proposal. The payload and cruising range were excellent, but the low speed performance was poor and the development risk was large, so it was concluded that this scheme was disadvantageous.

733-467

Boeing reexamined various SST configurations because the 733-290 type wing-tail separation type variable swept wing plan got stuck due to exhaust and tail interference problems. As a result, the draft 733-290 was integrated with the good part of SCAT15 to create the draft 733-467.

B2707-200

Boeing has proceeded with design studies such as B2707, B2707-100, and B2707-200, and solved problems such as steering stability. However, the weight increased and the cruising performance could not satisfy the required value.

SAT15F

Boeing added a horizontal tail to improve the vertical maneuverability of the SCAT15F to the standard value.

962-302

The delta wing with tail wing, 969-302, has the best payload and cruising performance because it can reduce its own weight. Since the wing span was large and the swept angle was small, the low speed performance was good.

969-404

The 969-404 proposal for the separate tail and wing variable swept wing has the best landing performance. However, there is a large risk of interference between the tail and exhaust, and it is structurally complex.

969-320

The 969-320 proposal based on SCAT15 could have the best payload and range, but the low speed performance was the worst. In addition, there was a significant decrease in handling stability due to aircraft deflection. Boeing, however, continued to consider the 969-320 proposal as a baseline for aerodynamic technology, including solutions for low-speed performance.

B2707-300

Boeing compared the 969-302, 969-320, and 969-402 plans, and selected the B2707-300 as the basic form of SST trial production.

Fantastic ! Thanks you very much again.

I recently had a crush on the SCAT-15F. It really was an aerodynamic wonder with a L/D of 10 against 7 for all the others, Concorde and Boeing included. NASA Langley had refined it over and over and it was a very fine aerodynamic job they had done. Even today it would held its ground as far as supersonic L/D goes.

But, alas, once out of the wind tunnel as mentionned

the low speed performance was poor

low speed handling was vicious.
Basically the aircraft stall was a SOB and it would slam into the ground at landing, faster than human reaction time.
I'm not sure even an analog FBW like Concorde could tame that beast. Yet in May 1972 flew a NASA Crusader with the first ever digital FBW, courtesy of former LM pilot Neil Armstrong now at NASA HQ.
What might have been...

Yes. Also one interesting stuff on the SCAT-15F-B7 from document AD478511 "NASA SCAT 15-F Feasibility Study" posted here #961 ,
is that a section of the leading edge slat seems to rotate upward :


never seen that before...

Just like Levcon on Teja

 

[blackkite]

I think this notched wing root leading edge was related to vortex lift at low speed.

Does Delta wing aircraft generate more lift than an aircraft with standard wings?

Answer (1 of 3): Typically delta wings have more surface area than swept wings of the same size, and lift generated is a simple matter of surface area, so delta wings indeed produce more lift than similarly sized swept- or straight-wing counterparts. The primary benefit of a delta wing, though, ...

I remember Miss SST and the made for TV movie that came from. As I also recall, one way they tried to make the plane for the movie look different from the Lockheed SST was to hang a set of 747 engines off of it. I'm not sure they didn't use a L-2000 cockpit mockup for the movie set as well, though.

that would be extraordinary. Mind you, the L-2000 mockup was dumped by Lockheed to the FAA, which brought it to its Oklahoma Office headquarters and used for passenger evacuation tests. That was in the early 70's. After the tests it stayed there, dilapidated, until it was finally scrapped.

More generally the L-2000 and 2707-300 mockups got really extraordinary (if not sad) adventures long after Lockheed lost to Boeing, and then Boeing lost to Mondale and Proxmire in the spring of 1971.
Both full-scale mockups were, after all, the closest thing from a SST America ever had.

Hi! Douglas 2229 SST model in Museum of Flying Santa Monica.

Its interesting that the Douglas 2229 looks more like the B-70 than does the NA60 from North American. I've read contemporary accounts discussing how the NA60 built on NAA's B-70 experience, but it's missing the fold-down wingtips and central engine box adopted by Douglas.

Yes Douglas 2229 SST was designed based on compression lift theory same as B-70.
Fuselage tail shape of Douglas 2229 looks like North American NAC60.
I think this shape increased vertical tail stabilizer area.

SCAT4 was Richard Whitcomb's idea. SCAT4 was a very advanced design.
I can see following SCAT4 shapes.

(2)Vertical and horizontal tail stabilizer with 4 engine type
