Откуда же. Потому как всегда считал их родственниками, как и кавасаки. Помнится вы даже не знали , что Боинг Вертол и Вертол Эйркрафт и другие фирмы Пясецкого одно и тоже.
Конечно. Особенно Як-24.
Я работал, а вы теоретик. Что тут не так, или вы работали в МВЗ? У Камова? В Казани, Арсеньеве?. И никого я авторитетом не давил, а давал ссылки. Которые вы мне контраргументировали фотографиями, которые конструктору дают ясную картину, какая мне была отлично видна, а вам нет почему-то.
Пожалуйста,
Construction of a prototype, designated Model 107, was started in May 1957, and this aircraft flew for the first time on 22 April 1958, powered by two 641kW Lycoming T53 turboshaft engines.
The first YHC-1B made its initial flight on 21 September 1961, by which time the first production contract for CH-47A aircraft had been placed. These were powered initially by 1641kW Lycoming T55-L-5 turboshafts
Что вполне укладывается сюда
By that time the US Army had become more interested in a larger, more powerful helicopter which Vertol had developed from the Model 107
Походу вы один так считаете. Оба medium lift .

By convention used worldwide, helicopters are categorized by weight. Specifically, "light", "medium lift", and "heavy lift" helicopters. Light helicopters are those generally considered below 12,000 pounds maximum gross weight. "Medium lift" are generally considered those from about 14,000 pounds to 45,000. There is some disagreement in terminology regarding the use of "heavy lift." Some within the industry refer to helicopters above 50,000 pounds as "heavy lift" while others reserve this term for the very largest helicopters, those above 80,000 pounds. Within Army aviation the largest helicopter is the 54,000 pound CH-47D Chinook, most often referred to as a medium lift helicopter.
