Mallard BASIC
It was also optimised for speed it is named after the LNER A4 class 4468 Mallard locomotive, the fastest steam locomotive in the world, once again displaying the company's fondness for railway-oriented nomenclature. (For instance, see the company name itself.) In fact the Locomotive name came from the phrase "To run like a train" and it was this theme that was used to name Mallard BASIC no other Locomotive product was named after anything railway-oriented.
Steam locomotive exhaust system
Andre Chapelon made a significant improvement with his Kylchap exhaust which incorporated a "Kyala spreader" (second stage nozzle) and third stage cowl between the blastpipe (first stage nozzle) and chimney. This became popular at the end of the steam era (early-mid 20th century) and was used on the Nigel Gresley's Mallard which holds the official world speed record for steam locomotives. Other contemporary designs include the Giesl, and Lemaître exhausts which achieve the same aim by different means.
