NAMC YS-33 Project

Hi,

in the same page from Flightglobal for the Hawker VTOL aircraft
I read that the Nihon YS-33 was a project of three engined
short-haul transport aircraft.
Has anybody a drawing to it ?.

Re: NAMC YS-33

Hi! I want to introduce you YS-33. This is already ended and unbuilt project, but very fascinating middle size transport. Middle engine nacelle shape is interesting.Mean shape of Tristar's and DC-10's.
This plane was planned to be a follow on project of YS-11 in 1969. It had three types, -10(106 passengers),-20(139 passengers, -30(149 passengers). Engine was three R.R RB203(4,524kg thrust).

Re: NAMC YS-33 trimotor airliner projects......

Dear Boys and Girls, here is an article in French about the NAMC YS-33 "projects" for a family of trimotor airliners......

The article comes from the 1st December 1969 issue of Aviation Magazine International......

Hi,

Flight International on-line archive has a lot of stuff over the YS-33 / Y-X. It is a long saga that started in 1965 and ended circa 1977 when Japan jumped into the 757 / 767 bandwagon.

Looks like they started with a jet-powered YS-11 then moved to a trijet aircraft. By 1977 they ended with a share of 15% into Boeing 767.

The Y-X project was first with the old NAMC company, but it was burdened by debt, so the Japanese government created a whole new entity, the CTDC, in 1973. Oddly enough, NAMC wasn't disbanded until 1982.

Establishment of the Civil
Transport Development Corporation,
with responsibility for the YX project
(as successor to Namco), by the
Japanese Ministry of International
Trade and Industry was approved on
March 30, and the company was
formally created on April 3 (1973)

Than you my dear Archiblad,

and for YX,please see;

http://www.secretprojects.co.uk/forum/index.php/topic,3749.msg29390.html#msg29390

From L+K 13/1973,

it was called YX-150.

From Technika Lotnicza 1970,

I think that,it was YS-33 and not YS-11

Your clipped article never identifies the illustrated aircraft by designation. For context, the article simply mentions that NAMC had been producing turboprop YS-11s for years.

A rough, machine translation follows:

The Japanese manufacturer NAMC, which has been producing YS-11 passenger aircraft with two Rolls-Royce Dart turbine propeller engines for several years, has now joined the project. The new aircraft will be powered by three Rolls-Royce RB.203 Trent turbofan engines with approximately 4,000 kgf of thrust, two of which will be mounted under the wing and the third in the tail section of the fuselage. The aircraft has a wingspan of 30.0 m, a length of 31.6 m, a maximum gross weight of 12,100 kgf, a maximum takeoff weight of 46,500 kgf, a maximum cruising speed of 800 km/h, and a range of 1,100 to 3,200 km. Versions for 134 and 149 passengers are also available.
