Bankstown 28th November 2009

[Grahame Hutchison]

Out at Bankstown this morning it was obvious that the fire season had started. Five firefighting choppers and Firescan 255, a Beech King Air, were all waiting or being prepared for action.

Bell 214B-1 N49732 (28005) 1976 model (Helitak 402) with belly water tank fitted. There was a ladder alongside each chopper, ready
for a quick get away.


Bell 214B-1 N214JL (28066 ) 1980 model registered to Helicopter Express in Chamblee Georgia (Helitak 404)


Bell 212 C-FVTS (Helitak 345)


Bell 212 C-FVTS (Helitak 345) with belly water tank fitted.

Sikorsky Skycrane S-64F N178AC (64097) 1970 model "Isabelle" registered to Erikson Air-Crane in Central Point Oregon. The crew were
preparing the aircraft and doing an engine run up.


Bell TH-1F VH-LIQ (66-1237) 1966 model operated by McDermott Aviation in Cooroy


Beech B200T King Air VH-LAB (BT-23) 1982 model (Firescan 255) operated by Astro Aerospace in Nowra. Note the additional electronics,
aerials and sensors on top of, and beneath the fuselage. Firescan departed from Runway 29C with a quite shallow climb out.

bottom of the rear fuselage is for an infrared unit. One of the crew members was filling it with liquid nitrogen while I was there, in
preparation for departure.

Hi Graham,
Nice pics :-) Maybe you can help...last Thursday I was driving from Blackheath to Katoomba when 5 Helo's crossed the road at no more than 50ft altitude...four red Bells (all with Kestrel titles - not sure on this point as I had to keep at least one eye on the road), other one was all blue.

Guessing one would have been C-FVTS...any ideas on teh other regos?

Many thanks
Wayne

Beech B200T King Air VH-LAB (BT-23) 1982 model (Firescan 255) operated by Astro Aerospace Nowra. This is a close up view of the
infrared sensor bay, the unit sits on the floor of the cabin opposite the rear door. They had a large metal cannister of liquid nitrogen
which they used to fill a flask sized container, from which they poured the liquid nitrogen into three small funnels on the top of the unit.


Other interesting aircraft on the apron this morning are below.

Beech B200 VH-MSZ (BB-866) 1981 "Fred McKay" operated by the RFDS Essendon.

Some more information on infrared sensors and the use of liquid nitrogen.

From www.FreePatentsOnline.com

"An infrared detector includes an outer cylinder having an infrared permeable window and an inner cylinder accommodated in the outer cylinder. The inner cylinder has an end surface, a cylindrical side surface, and an annular tapering surface formed between the end surface and the cylindrical side surface. The annular tapering surface has a diameter continuously decreasing toward the end surface. A multiple element type infrared sensor is mounted on the end surface of the inner cylinder, the infrared sensor having a plurality of output electrodes. A cryogenic cooling arrangement is provided for cooling the infrared sensor to low temperatures, and a signal fetching arrangement is provided for carrying a signal detected by the infrared sensor, the signal fetching arrangement including wiring patterns formed on the end surface, the tapering surface and the cylindrical side surface of the inner cylinder. The tapering surface of the inner cylinder is mirror-finished, and the wiring patterns are formed by laser-cutting a gold thin film deposited on the inner cylinder."
