Hi,

I find anther report for this convertiplane,and they also called it D-210,
but I can't ID if this means design-210 or not ?.

They call it D210, not D-210... and we're not even sure this corresponds to a Model number.

Abstract:
Results of conceptual design studies of commercial rotary wing transport aircraft for the 1985 time period are presented. Two aircraft configurations, a tandem helicopter and a tilt rotor, were designed for a 200 nautical mile short haul mission with an upper limit of 100 passengers. In addition to the baseline aircraft two further designs of each configuration are included to assess the impact of external noise design criteria on the aircraft size, weight, and cost.

Abstract:
Results of conceptual engineering design studies of a STOL tilt rotor commercial aircraft for the 1985 time frame are presented. The details of aircraft size, performance, flying qualities, noise, and cost are included. The savings in terms of fuel economy resulting from STOL operations compared with VTOL vehicles are determined.

What I always found interesting about designs from those early days is that Bel's designs tilted the engines while Boeing's designs didn't. There are pros and cons with either concept.
 
In the documents I was looking at the preliminary design was referred to as TH-100 with the design in the Op being referred to as TR-100, so my mistake is an honest one. Feel free to merge this with the older topic.
 
How can anything so interesting be a mistake? ;D

I guess we'll see a topic merge soon?
