to actuate two independent air brakes, in the upstream portion of the air circuit, i.e., nearer to the compressor, than the first and second check valves, which safety device is composed of (1) a differential piston, having two opposite directionally positioned pressure receiving surfaces, bein...
These were also provided with air brakes. While these units were supposed to be removed during firing, the crew would often not remove them, as it was easier to move the gun quickly if needed. This was only possible when engaging targets at low gun elevations. Aerial targets could not be...
The primary function is to operate the locomotive and railcar brakes. Several air compressors currently used in the railway industry are designed with an unloader system which, when activated with pilot air pressure, will, under normal operation, release the air pressure contained or “bottled” in...
But he said the marks were similar to the marks left by aircraft doing up and down the runway without using brakes. He said he could not account for survivors evidence which said they had felt brakes being applied before the aircraft hit the sea. Mr. Coombs told the inquiry that his ...
The second point in a big deal is checking the brakes, steering systems and suspension. This is especially true after our winter, changing roads to holes. They loose the suspension and knock off the correct wheel alignment. Checking the condition of the wheels Pay close attention to the condit...

Unfortunately, all the information in the chart below only refers to the risk of death and does not account for the risk of injuries. The reason is simply the fact that data about injuries are extremely unreliable since the great majority of sport injuries are never reported and/or accounted ...
max pressure is simply: pmax = patm * (Vmax/Vmin)^n, where patm is atmospheric pressure (say this is the last stage of expansion), Vmax is volume at fi = 30° (we have 6 vanes) and n is 1.30. it would be possible to make this thing run very smooth (like putting vanes on rol...
I am fortunate that my glider has very powerful airbrakes, which allow for a very steep descent if necessary. This approach may not work for gliders with less effective spoilers. Learning From My Own Mistakes I looked through my own inflight videos and found the following one from a flight...
“I have the impression we have speed” then moved the thrust levers to the IDLE detent. He reformulated his impression a few seconds later, combined with an attempt to extend the speed brakes. Other factors which may have prompted the PF to fear an over speed situation were: The display ...
