This is a typical cautious, (over 30secs.), first start of a brand new TJT 3000 using a new Fadec autostart ecu. The video is quite long at over 5megs. but does show quite well how the ecu increases and reduces fuel pump voltage, (lower right of display), according to the temperature trend. This is shown as % of ecu NiCad pack voltage, 1000 being 100% pack voltage and 010 being 1% pack voltage. During the start and running sequence the ecu reacts in real time to increases or decreases in temperature, rpm and throttle stick position and will accelerate/decelerate the engine as quickly as possible while keeping within the user set temperature and rpm parameters.
Top left of the display is the current part of the engine running cycle, (between start and shutdown), that the ecu is controlling and is fairly self explanatory. Also shown here will be any shutdown data such as flameout, etc.
Top right of display is the exhaust gas temperature, (egt), shown in deg.celcius.
Bottom left is rpm shown to the nearest 100 rpm.
Bottom right is as described above the fuel pump supply voltage shown as % of current pack voltage.
This short 750k clip shows the huge 150lb Vulcan flown by Dave Johnson on a half power fly-by. This was only the second turbine powered test flight at the Rolls Royce Hucknall runway. Despite the huge drag of the Vulcan's massive airframe the 2 TJT's have no problem powering it in a very scale like manner. The Vulcan has now had dozens of flights at most of the UK shows during the 2003 display season and will continue into the 2004 season.
Short MPEG of the big Vulcan landing at the Bruntingthorpe, U.K. runway after entertaining the crowds in support of the Vulcan back to the sky project. The eagle eyed may spot the Hadley Page Victor in the background.
