Дальняя транспортная летающая лодка
Saro SR.45 Princess
Превосходившая размерами летающую лодку Martin Mars и весившая больше, чем сухопутный авиалайнер Bristol Brabazon I, огромная летающая лодка Saro SR.45 Princess, три прототипа которой были заказаны в мае 1946 года, стала одним из последних представителей тяжелых гидросамолетов. Силовая установка машины включала десять ТВД Proteus - одиночных во внешних гондолах и спаренных в средних и внутренних гондолах. Экипаж состоял из шести человек (два пилота, два бортинженера, радист и штурман) и 105 пассажиров в салонах первого и туристического классов при двухпалубной компоновке кабины.
Первый прототип Princess (G-ALUN) поднялся в воздух 22 августа 1952 года. Однако из-за проблем с разработкой редукторов спаренных двигателей было принято решение прекратить работы. Второй и третий прототипы Princess не летали и были законсервированы.
Летающая лодка Princess была предназначена для беспосадочных трансатлантических линий компании BOAC. Но появившиеся после войны сухопутные лайнеры показали, что могут работать на этих маршрутах с большей экономичностью, не уступая по безопасности летающим лодкам, что свело на нет интерес к последним. В результате машина была построена как дальний военно-транспортный самолет для британских ВВС, но проблемы с силовой установкой не позволили реализовать и этот вариант, и дальнейшая разработка была прекращена.

Регистрационный номер : G-ALUN [28] Saunders-Roe’s S.R.45 Princess G-ALUN was an all-metal flying boat powered by ten 3,780 h.p. Bristol Proteus 600 engines. Brian Cox took a five-bob trip round Cowes harbour in September 1952 and took this pictures. The evening sunlight and the busy atmosphere make these photographs particularly pleasing. Fifteen years later, after years of speculation as to its future, G-ALUN was towed by tug to a breaker’s yard at Southampton, where the last of the line of great British flying boats was reduced to scrap.

A colour-reversed section of a 1958 Convair blueprint detailing the incorporation of a nuclear powerplant into a Saro Princess flying-boat. Convair was to provide the reactor and heat exchangers; the aircraft was to use Pratt & Whitney T57 engines, which could use either conventional fuel or heat from the reactor’s heat exchangers.
