Could The 757 Have Been Shrunk?

What would had been the feasibility of shrinking the B757 into the B737s size category instead of launching the B737NG?

Say Boeing "E-jets" the 757 and gives it a different (smaller) pair of wings, smaller engines, smaller landing gears, and maybe a smaller tail?

It's a 3-3 configuration, and it's aerodynamics should probably be superior to the B737 as it is a newer design (more A320/E-Jets/787 looking).

Feasible? Or is the 757 designed to be much larger from scratch?

Sounds to me like you just described a 737NG with a 757 cockpit section. I think I recall the 737/727 cockpit section is actually more aerodynamic than the 757 section. Boeing made slight trade off with the 757 so they could have a common 757/767 cockpit.

Wow, wouldn't that be a rocket  Wink

You'd probably get true intercontinental range out of the thing...like not just US East Coast to Western Europe.

As the 757, when launched, was designated as the -200 series, does this imply that a series 100 had been contemplated but was not favoured by any customer airlines at the time?

i believe the original 100 series airframe would just have had far too much muscle. RB211s on a plane the size of a 737-800? we'd have seen climb rates topping 15,000fpm... Big grin

A shrunken 757 would have been much heavier and more expensive than the 737NG with similar capacity, thus not the most economic solution. Significant shrinks (e.g. A318, 737-600, 747SP) have rarely been successful or sold in more than token numbers for specific niche markets.

Actually, you would probably have to have a LARGER tail. When you shrink the length of an aircraft, you loose part of the moment arm that the rudder acts upon. Thus, you would need a larger control surface to compensate (i.e. 747SP).

The 757-100 was the original planned version of the aircraft, a -150 seater, nobody wanted it when they saw the economics of the -200.

Yes and no. They have not sold in significant numbers but their success cannot be measured thus. The have (we assume) yielded a good rate of return on the investment of developing them.

the new airplane's name : 737NG  Smile

the 739 is very close to the 757 and the 757 simply wouldnt go smaller..

Yes there was a -100 design study. The wing was too big and the landing gear was too heavy.
