Glad you liked the shot! Β It was kind of rare seeing the 'Busses"!

This is a very interesting shot with the parachute deployed. Did they normally open the canopy while the chute was still out?
Nice shot!!

Usually the acft would jettison the drag chutes as they cleared the runway at their home base.
These would be gathered up by the EOR crews and repacked at a back shop.
When they were transient, they would keep the chute so the transient alert crews could have it repacked as they serviced the jet.
Fighter acft (up to the modern F-15/ F-16 vintage) had ineffective air conditioners once power was brought back to idle, so they would taxi back w/ the canopy open.
I am not sure if you are familiar with air cycle machines, but here is an explanation from an earlier journal entry of mine here:
Β
Block 25 F-16C/D ModelsThe Block 25 was a radical departure in avionics and weapon system capability from the Block 15 A/B model aircraft. There were some minor structural differences, but the powerplant was still the P&W F-100PW200 engine from the A/B models.
Later mods to the block 25 removed the PW200 engine and allowed the installation of the F100PW220/ 220E engine. This engine had a full authority digital fuel control as well as a heavier core and more robust main fuel gear pump for longer life and higher fuel flows.
The -220E was a -200 motor rebuilt into a -220 standard.
The cockpit was completely redesigned with a bigger HUD, as well as relocation of all of the fire system data entry keypads to the base of the HUD, from the F-16A/B's location under the throttle area. This was called the UFC (up front controls) and IKP (Intergrated Keypad). The UHF and VHF radios could now take inputs for channel changing to UFC.
Two large MFD's (multi-function displays) replaced the dedicated stores control panel and
"Air cycle machine ECS systems use a turbine that runs off engine compressor bleed air. The turbine is connected to a compressor disk that greatly compresses and heats the incoming air. This air flows to an expansion chamber as it exits the turbine compressor. This chamber rapidly expands this air. This rapid expansion of the air takes on heat. This cycle will cool compressed air at several 100's of degrees at the compressor outlet to 30 degree air. In fact to have heat, hot air must be mixed with the cold, since the physics of an air cycle machine will only allow a discharge temp of 30 degrees!"

So, if I understand it right, the sudden injection into the expansion chamber causes the air temp to drop. Yes?
Some pretty complex stuff!

ACMs are a pretty simple system. It is an elegant way to condition air!
