Bombardier Dash 8
The Bombardier Dash 8 is a high wing twin engined turbo-propeller airliner. It was developed by de Havilland Canada in 1984 as a replacement for their Dash 7 airliner. The Dash 7 was a four-engined turbo-propeller regional airliner and its strength lay in the ability to perform short takeoffs and landings which de Havilland saw as a strong selling point in some of Canada’s more remote locations.
The market actually felt differently and was more interested in operating economy, rather than short field operations. This resulted in them coming up with the Dash 8. The Dash 8 took some of the features of the Dash 7, such as the basic fuselage, and the tail section, but instead of four turboprop engines they reduced this to two more powerful engines. The nose of the Dash 8 was more streamlined than its predecessor coming to a point toward the bottom of the fuselage.
The engine nacelles are long and streamlined protruding fore and aft of the high aspect wing. The landing gear is stored in the after section of each nacelle and retracts toward the rear. Like the Dash 7 the Dash 8 has a large T-shaped tail which ensures that the horizontal stabiliser is kept out of the propeller wash during take-off.
The Dash 8 was a much more attractive design to the market due to its operating economy. This was in large part due to the reduction from 4 to 2 engines. However, the Dash 8 also out performed the Dash 7 in its cruise capabilities and was the most fuel efficient regional airliner of any type, when it was introduced.
The Dash 8 came along at the right time to take advantage of the end of life of old regional turboprop airliners. These included the Fokker F27 Friendship and the Handley Page HPR-7 Herald 214. There is quite a similarity in airframe across all these models. This made it an ideal upgrade option for those airlines that needed to replace the older models as they came to the end of their service life.
At the beginning of its life, the Dash 8 was manufactured by de Havilland Canada and carried the name DHC Dash 8. It was and still is manufactured in Downsview on the north side of Toronto, Ontario. The company was taken over by Boeing in 1988 for several reasons, one of which was that Boeing was competing with Airbus for a large airliner contract with Air Canada. The deal was won by Airbus and subsequently, Boeing sold de Haviland Canada in 1992 to Bombardier Aerospace. The aircraft type is now known at the Bombardier Dash 8 or Q-Series.
Bombardier Dash 8 Variants
Since its introduction in 1984, there have been four main variants of the Dash 8. The classic versions which include the Dash8 -100, -200 and -300 have now ceased production while Bombardier concentrates development on the 400 or Q400 as it is more commonly known. The 100 and 200 were of equal length with a much shorter fuselage than the later models. The main difference between the 100 and 200 was an increase in engine power giving better cruise performance but slightly less range.
The -300 was just over three metres longer than the 100 and 200 with a slightly lower cruising speed. It came with the option for standard or long range fuel tanks where the standard option gave a lower range than both the 100 and 200, but the long range was significantly higher.
The 400 is the current model that Bombardier say they will develop further for the future. At over 7 metres longer than the 300 with a significantly higher cruise speed, the 400 is a very attractive option for regional carriers. Even when compared to regional jets, the 400 is an attractive option with better seat/mile economy. When many regional routes are less than 500 kilometres, a large proportion of the trip is spent taxiing to and from runways. This means that what little speed advantage the regional jets may have over the 400 becomes quite insignificant.
Bombardier is marketing the 400 quite aggressively now and is considering a further stretch, the 400X. There are really only two aircraft in this turboprop space competing with each other, the Dash 8-400 and the ATR 72.
Since the first half of 1996, 200, 300 and 400s have been fitted with ANVS (Active Noise and Vibration Suppression). This system works to reduce the noise and vibration that is common in propeller aircraft. It works a little like noise cancelling headphones but on a larger scale. This enhances the cabin experience to almost the same level as jet airliners. The aircraft that carry this feature are denoted by the Q for quiet in their model number, such as the Dash 8 Q400.
