Hello
Team!
Through
the gracious cooperation and involvement of world class balloonist Troy
Bradley, we have a gas flight scheduled to launch next Friday night! This
isnÕt the gas *cluster* flight IÕve been talking about, but a gas flight that
leads up to the cluster flight.
In
preparation for my gas cluster ascension, I was very fortunate to connect with
Troy, a world-recording holding gas balloonist. Among his accomplishments
are the 58 world records in ballooning he has set. In the 1992 Chrysler Trans-Atlantic
balloon race, Troy flew 3,318 miles, and became the first to fly a balloon from
North America to Africa; he set the absolute world duration record for manned
balloon flight at 144 hours 23 minutes [can you imagine flying that long--over
six days--straight?]; Troy has set the AM-8 through AM-15 records for duration,
distance and altitude; Troy won the first U.S. National Hot Air Team
Championship, and he has participated in 7 Gordon Bennett Gas
races, 6 America's Challenge Gas Balloon races-- and he won the 1998
America's Challenge Race. He has 4,600 PIC hours, and has flown in 45
States and 12 countries, flying over 11,000 passengers. Ok, this whole
e-mail could be a list of his lighter-than-air accomplishments!
IsnÕt
this amazing, to have this flight, and this guy, coming out with his
balloon? This is like taking up golf, and having Tiger Woods come to give
you lessons. Oh, youÕre starting to play basketball? Michael Jordan
is willing to come by and give you some tips on your jump shot.
But,
getting to the upcoming flight: Troy owns a 14,000 cu/ft gas system,
which is now shipping from Albuquerque, New Mexico to us here in Raleigh, North
Carolina. The gas is ordered, and scheduled for delivery on Friday.
After the balloon arrives, Troy will be joining us for a flight scheduled for
inflation late night on Friday, May 9th.
Your
participation in that flight would be welcome.
This
flight will allow me to test so many things. The intention is to fly in a
standard basket hanging below the ÔlargeÕ 14,000 cu/ft helium filled balloon,
which will be providing the majority of the lift. In addition, I will
attach two of my gas cluster cells to the gondola, providing some minor additional
lift. (20-30 pounds)
This
will allow me to:
-
Test the
inflation of two 8-foot, 268 cu/ft cluster balloons, inflating off of 219 cu/ft
ÔKÕ helium tanks. One balloon will be filled via an open-mouthed
quick-fill hose, and the other will be filled using the micro-vent fill system.
-
Test actual
lift produced, compared to previous tests. (Calculations show net lift *should*
be 13 pounds per balloon; last test, we observed only 9 pounds.)
-
When taking
the balloons to altitude, I can see what the 8-foot cluster balloons do at
altitude. (e.g. do they burst?)
-
Test the
Ômicro ventÕ on one of the balloons, to see how smoothly it vents gas, and the
rate of gas venting / lift reduction
-
Test to see
if the balloons rigged with micro-vents leak
-
Observe the
rate at which the helium diffusions occurs through the chloroprene balloon
membrane, and observe the rate of resulting loss of lift
-
Pop one
balloon! This system is approx 14,000 cu/ft. My cluster system will
be approx 12,000 cu/ft. So, the overall displacement is not entirely
dissimilar. By popping one balloon on this flight, while flying level, I
can observe the resulting change in altitude, rate of descent, etc. Is it
severe, or smooth? (I believe it will be severe.)
-
Gain
aeronautical experience flying gas, flying with a tremendously experienced gas
pilot!
-
Gain
ground-school / theoretical knowledge of flying gas
-
If
everything works out right, - remove the Ôairborne heaterÕ restriction from my
pilots license [For non-pilots: when getting a lighter-than-air license, one
typically first gets a ÔLighter than air, Free balloonÕ rating, allowing a
pilot to fly balloons with the restriction that the balloon must have an
Òairborne heaterÓ—that is, a burner that burns some fuel (propane) to
heat the air in the envelope, making the Ôhot airÕ which defines a hot-air
balloon. To legally fly standard gas balloons, you need to have this
restriction removed. ]
-
Verify that
the gas provider really can deliver the gas when they promise; also, acquaint
them with the delivery location and logistics
-
Test the
satellite tracking device, with remote observers tracking the flight on their
home computers
-
Fly in my
local North Carolina area along with a very experienced gas pilot, to become
more familiar with some of the flying area within gas range
-
Build
relationship with the drop-zone where we will be flying out of; ensure that it
works ok to have 50-60 tanks of helium delivered there.
Details:
Launch
Site
The
launch location is to be Carolina Sky Sports, in Franklinton North
Carolina. This is a skydiving facility, located approximately 20 miles
north of Raleigh. (Between Franklington and Louisburg.) The owners
of Carolina Sky Sports have graciously agreed to allow us to have the helium
banks delivered to their facility, and launch from their airfield. (There
are no skydives going on anywhere near the time of our flight.) This is
an awesome facility, with a large skydive landing zone/field, paved runway, a
number of jump-aircraft, and amazing personnel. It is also marked on the
sectionals as an area with dropzone activities, and the local air traffic
control guys are well familiar with this site.
Inflation
and launch time:
We
intend to inflate very late at night on Friday, May 9th. (e.g.: just
before midnight.) Then, our launch will be shortly after, in the early
pre-dawn hours of Saturday May 10th.
Flight
profile and time:
Intention
would be to fly comparatively low-altitudes (non-oxygen) through past dawn,
with landing perhaps around 10:00am the next day (Saturday), before thermal
activity gets too stirred up.
Of
course, if we run out of land—i.e., we are approaching the coast of the
Atlantic ocean—that would end our flight early.
Helium
I
was unable to get a tube-trailer without spending a tremendous amount on
delivery. Instead, Praxair will be delivering (48) 291 cu/ft ÒTÓ bottles,
grouped into helium ÔbanksÕ. They take the individual bottles, and
assemble them into a bank of 12 cylinders. Attached to the valve on each ÔTÕ
bottle is a pigtail leading to a single header. So, you open each bottle,
then open the single header, and fill the balloon until that bank is
drained. Then, you move onto the next bank of 12 bottles, until the tanks
are empty and the gas has been transferred to the balloon.
Airborne
heater restriction:
If
everything goes smoothly and to-plan, I hope to meet the following requirements
and have the restriction removed:
FAR 61.105 Aeronautical knowledge
FAR 61.107 (b) (8) Flight proficiency
FAR 61.109 (h) (1) Aeronautical Experience
(1) at least 2 flights of 2
hours each (meaning we will need an intermediary landing.)
(ii)
one flight performing Pilot In Command duties, with an authorized instructor.
(So, this would be the flight after the intermediary landing, with me as PIC,
along with Troy in the basket as the instructor)
(iii)
one flight involving a controlled ascent to 3,000 feet above the launch site
Aircraft:
N3027Z;
14,000 cubic foot Helium rated balloon; Certified Experimental; Spring
actuated disk valve; rip deflation port; quick-fill (not a ÔnettedÕ balloon).
Troy has actually set three world records in this balloon: Distance
(Amarillo, Texas to Pittsburg, Pennsylvania – 1,200 miles); Duration (46
hours 50 minutes.) DoesnÕt that duration record sounds more like an
endurance record? Flying solo for nearly two days straight!
Transponder:
No
transponder.
ATC/Airspace
–
I
have contacted the good controllers at the RDU airport and informed them of our
flight plans. We intend to stay clear of the Class C airspace surrounding
RDU. However, the controller in the RDU tower said it would be Òno
problem whatsoeverÓ to fly through or above their airspace; they just requested
we give them a call a couple of hours prior to flight, so they know we are in
the area. (IsnÕt that cool?) There are likely to be no normally scheduled
commercial flights at that time, except perhaps the odd UPS or FedEx plane.
Tracking
The
day before the flight, I will send out a URL where you can track me in
real-time from home; the track images are overlaid on Google Maps, so you can
see the flight! Provided the equipment works, I will be sending up to 3
types of messages: ÔOkÕ just means I have just pressed the button, and I am
flying fine; ÔHelpÕ means I am requesting non-emergency retrieval from my
crew. Then there is the 911 beacon, which notifies search and rescue, and
is only for life threatening emergencies where self-rescue options have been
exhausted.
Crew
and guests:
Guests
at the inflation, and chase crew on the road, are welcome! In fact, if
you would like to crew for the upcoming gas cluster flight, this would be an
ideal time to become acquainted with the area and gas procedures; Please
contact me if you would like to be present, so I make sure you receive the most
up-to-date information. Please provide a contact phone number.
Thanks,
and I will send out the tracking URL the day before the flight!
