Morton<\/i> balloon has crossed the longitude of 163 degrees east and is currently flying in New Zealand airspace.\u00a0 Last night, the pilot Fedor Konyukhov left the Green continent in the hopes of circumnavigating the globe and returning to welcoming Australian soil.\u00a0 When Fedor was crossing the coast, air traffic controllers farewelled him on their radio frequency and said: \u201cgood luck, Fedor\u201d.\u00a0 An hour later, the balloon flew over Lord Howe island.\u00a0 Currently, the ground crew is keeping in touch with air traffic controllers in New Zealand (Auckland).\u00a0 We received permission to fly at FL 260 (26,000 feet) or 7,924 meters.\u00a0 We are satisfied with this flight level for today.<\/p>\n

Now that the Morton<\/i> balloon is over the ocean, we have the opportunity to take a breath and look back at the 3 day and 5000 km long flight.\u00a0 We will also try to answer some questions that we received here at the Flight Control Centre.<\/p>\n

Why was Fedor flying at the height of 6,700-7,000 meters during the first few days? \u00a0The media announced a flight level of 8,000 meters\u2026<\/b><\/p>\n

These flight levels have been calculated on the basis of the maximum take-off weight of the balloon (MTOW), at 9762 kg. \u00a0In order to rise above 7,000 meters on the first day (for example to 8,000 meters) we had to leave behind a few fuel cylinders (filled with propane) to the equivalent of 5 days of flying.<\/p>\n

Morton<\/i> balloon took off with the maximum fuel load of 35 steel cylinders of propane. \u00a0Total fuel weight was 5,355 kg.<\/p>\n

\"\"<\/figure>\n

How is the weight of fuel calculated?<\/b><\/p>\n

Breakdown of the fuel weight: each steel cylinder weighs 49 kg. \u00a0The cylinder is pumped with 94 kilograms of propane gas. \u00a0In addition, about 10 kg of ethane is pumped into each cylinder. \u00a0Ethane is added to propane for the purpose of improving the overall saturation vapour pressure of the gas mixture, in order to avoid reducing the gas pressure in the cold (Morton<\/i> balloon flies in sub-zero temperatures at all times). \u00a0So, the total weight of each cylinder is 153 kg (with small tolerances) x 35 = 5,355 kg.<\/p>\n

What are technical parameters for the gas envelope? \u00a0How heavy is the shell?<\/b><\/p>\n

A fully assembled shell weighs 1, 628 kg. \u00a0The volume of the gas compartment is 15, 575 cubic meters. \u00a060% of the volume of the gas envelope has been filled with helium just before the start. Considering the height, when heated by the sun the helium considerably increases in volume, so the pressure inside the balloon is formed. \u00a0Excess helium is automatically pitted through appendices (the sleeves on both sides of the ball). \u00a0At the start we pumped in approximately 9,700 cubic meters of helium.<\/p>\n

Buoyancy of helium is as follows: 1 m\u00b3 of helium lifts 1 kg of weight. \u00a0At night before the start our team pumped helium until the balloon reached the state of equilibrium (the state of equilibrium is when the balloon does not rise, but is not touching the ground). \u00a0At dawn Fedor ignited the burners and the balloon journeyed into the sky.<\/p>\n

Why so many cylinders?<\/b><\/p>\n

For the first leg of the trip, just to cross the Pacific (from Australia to Chile) Fedor would have only required a quarter of his current propane stock as you could fairly accurately predict the height and strength of the jet stream for most of this route. \u00a0However, Fedor endeavours to fly around the world. Due to this huge distance many uncertainties lay ahead of him.<\/p>\n

No meteorologist or computer model can forecast the speed or direction of the wind when flying a route of 30,000+ km. \u00a0Weather forecasts are reliable up to 5 days maximum. \u00a0We will not be able to avoid unexpected changes in velocity. Therefore, Fedor will not be able to fly around the world in a single jet stream.<\/p>\n

(A brief note from Alex Vikulov, a member of Fedor Konyukhov\u2019s expedition HQ and a former BoM meteorologist: \u201cJet streams are fast generally westerly air currents found in the upper troposphere.\u00a0 They are constantly meandering, may develop and dissipate, split in two or more streams, combine into one stream and even develop closed circulation eddies\u201d.)<\/p>\n

Estimated fuel consumption is 1.5 cylinders per day. \u00a0So, the total fuel reserve gives Fedor 23 days of flying. \u00a0Currently Fedor is on track in regards to our fuel consumption estimate.<\/p>\n

Previously there were only two successful around the world balloon flights:<\/p>\n

One took place in the Northern Hemisphere in 1999 and it took them 21 days to complete the flight (two pilots).<\/p>\n

The other took place in the southern hemisphere in 2002 and it took him 13 days (one pilot).<\/p>\n

We hope for the best but are prepared for any situation. \u00a0Our estimates were based on a conservative scenario. \u00a0The first three days over Australia have demonstrated that our conservative approach to fuel reserves was accurate.<\/p>\n

Could you have revised the launch window?<\/b><\/p>\n

No. \u00a0A huge shell, consisting of three sections, has been assembled and filled without fail.\u00a0 The lift-off of the balloon was executed perfectly. \u00a0The climb happened according to plan. \u00a0The pilot has tested all systems during the first two days of flying. \u00a0Everything has now been fixed and calibrated. Australia astern. \u00a0Fedor is flying over the Pacific Ocean with New Zealand on his starboard side, at a current \u00a0height of 7500 meters and speed of 130 km per hour.<\/p>\n
