Some pictures of the Mainlander visioned in BAF scheme with a 3-View can be found on Google:
Fairey Britten Norman Mainlander:
Fairey Britten-Norman proposes a Hercules-size Bristol Freighter replacement with a Trislander-type layout:
"The aircraft was designed to carry 100 passengers or ten tons of freight or vehicles over 250 miles, 400 km at 200kt, 370 km/hr. At the maximum take-off weight of 62,5001b, 28,500 kg and sea level, ISA plus 20 °C, the unfactored take-off distance to 35 ft is 2,250 ft, 685m. It was to be powered by three Rolls-Royce Dart RDa7s rated at 2,280 t.e.h.p.(wet) arranged in a layout similar to that of the company's Trislander design."
This is not to say of course that the 4 engined version of the Islander as illustrated in ferrydude's reference wasn't also included in a study under the same title. ( The BN4 looks like being inspired by "Dove to Heron" and bears no resemblance to the three turboprop scheme ).
Treadigraphs Triloader is a much later design from 1991 ( and new to me), indeed looking a lot like a cross between a big Skyvan and a Trislander.
All interesting concepts.
