| Subject: | Yak 52 Weight and Balance. Help? |
Hi Yakmen
Please could someone assist me with a workable Yak 52 weight and balance table.
I tried figuring out the one on yakuk but can't make sense of it.Especially when
I see that the excel spreadsheet says NOT OK when I am only 1 up with full
tanks. In particular what I am interested in is calculating CG position with
two up and a smoke system...Please could someone assist.
Best Regards
Jason

I thought I posted this to the list, but apparently I replied directly to
someone. So for those of you who are interested.
Nothing I've done here is of my own invention, all I'm doing is leveraging
what the paintball community has been doing for years.
For example, I have another idea for the emergency system that I'm
contemplating. Firefighters use a much smaller Carbon Fiber bottle (98
Cu/In) for emergencies in case their main breathing apparatus fails. It is
sometimes referred to as an "Oh Shit" bottle. It is meant to supply 5 min
of breathing air. It weighs about 2 lbs and fits in the palm of your hand.
These bottles have a working pressure of 4500 Lbs. Total volume of air in a
cylinder is the result of initial volume multiplied by the pressure. For
example our stock spherical bottle in our CJ has a water capacity of 3
liters, or about .1Cu/Ft. At 750 PSI that equates to about 5 Cu/Ft of air.
The storage volume for a compressed gas can be calculated using Boyle's Law:
*pa Va = pc Vc (1)*
*where*
*pa = atmospheric
<http://www.engineeringtoolbox.com/stp-standard-ntp-normal-air-d_772.html>
pressure
(14.7 psia,* *101.325 kPa**)*
*Va = volume of the gas at atmospheric
<http://www.engineeringtoolbox.com/stp-standard-ntp-normal-air-d_772.html>
pressure
(cubic feet, cubic meter)*
*pc = compressed pressure (psi,* *kPa**)*
*Vc = volume of the gas at compressed pressure (cubic feet, cubic meter)*
*e.g. 750 psi x .1Cu/Ft / 14.7 = 5.1 Cu/Ft*
5.1 Cu/Ft is the total volume of air that is required to blow down the gear
and have some left for flaps and brakes.
Now take the same equation and apply it to the mini bottle. .057 x 4500 /
14.7 = *17.4 Cu/Ft* !
This means that the tiny little bottle has the potential to hold 3 times
the amount of air as our stock system.
But wait you say....I can't use 4500 PSI in my system.......Well yes you're
right whoever you are.. But the paintballers come to the rescue again.
Their guns can't handle 4500 PSI either, but coincidentally they work at
around 800 PSI. The paintballers have developed small regulators that screw
into the bottle and reduce the pressure to the lower pressure usable in our
airplanes.
In order to use this you would give up charging the emergency system from
the on board air system however. This would be a system where you would
need to recharge after an emergency deployment. The bottle would be
deployed in the cockpit replacing the emergency air valve and plumbed
directly to the emergency circuit. Total loss systems were common in many
airplanes, The Mig15 comes to mind.
This setup however would eliminate several sources of problems/leaks
including:
The Air Valve (Can't hold emergency air?)
The Check Valve (Can't get your gear up????)
It would also eliminate the Tee from the main air system, and all the
tubing and weight from the tail. So basically it is a much simpler system,
albeit 1 shot, actually 3 shots.
The bottle can be easily unscrewed for recharging at your local firehouse
or paintball or scuba store (Yes 3000 PSI would work but not as many blows).
During annual inspections when you're doing multiple blows you can just
recharge from your own Scuba bottle to 3000 PSI a butt load of times.
And best of all A brand new bottle and regulator is about $200, available
on Amazon, and all it takes is a few adapters to fit in our airplane.
The Main Air tank at 750 PSI contains 20 Cu/Ft of air. As a bonus you could
carry a spare mini bottle in your luggage, which you could use to replace
the emergency bottle after a blow, or in a pinch, you could fill your main
air tank enough to get you started! It would be about 3 Cu/Ft short, but
we've all started with less than full tanks.

Now here are some caveats.
Both solutions use the Carbon Fiber wrapped aluminum cylinders. The Carbon
fiber is what allows the higher pressures. They have a DOT requirement for
Hydro checking every 5 years. Steel cylinders are every 3 years.
Carbon Fiber wrapped cylinders have a life limit of 15 years, but this is
for commercial use at 4500 PSI. The main air bottle will never be
pressurized beyond 750 PSI so it should last indefinitely. The emergency
system would be fully pressurized, but I can spring for $200 bucks every 15
years.

Sam,
Good question. Unfortunately High Pressure tanks have to be seamless so a
drain port is not a possibility. This is why it's important to keep your
air dryer serviced. But since it's aluminum rust isn't an issue. Would have
to make it part of the annual service routine to remove and dump.

=9CSince it=99s aluminum rust isn=99t an
issue=9D. That may be the case but only if it is pure aluminum
which is protected from corrosion by it=99s own oxide layer. If
it is an alloy that protection is seriously degraded depending on the
alloy composition and strength.
Pure aluminum has a strength something like cheddar cheese. However if
the entire strength of the tank is derived from the carbon fibre
wrapping then pure aluminum would be suitable.
Something to consider.

Drager 4500 PSI 60 min Carbon Fiber Wrapped Aluminum Tank.
Weight 10 lbs
Length 21"
Diameter 7"
Hydro Tested to 7500 PSI.
Fittings:
Stainless Steel SCBA to NPT Adapter

This should fit in the same bracket where the stock tanks lives. All
