Black Wind - Cussler Clive (читать книги онлайн без сокращений TXT) 📗
To the casual observer, the first sign of an imminent rocket blast off the Sea Launch platform is the roaring rush of fresh water as it is pumped into the deluge system. At T-5 seconds, a veritable flood of dampening water is released into the flame trench positioned beneath the launchpad. The effect of the massive water dousing is to lessen the thrust exhaust effects to the platform, and, more important, minimize potential acoustic damage to the payload from the maelstrom at launch.
At T-3 seconds, the Zenit rocket begins groaning and stirring as its internal mechanisms are activated and the massive rocket comes to life. Inside its metal skin, a high-speed turbine pump begins force-feeding the volatile liquid propellant through an injector into the rocket engine's four combustion chambers. Inside each chamber, an igniter is activated, detonating the propellant in what amounts to a controlled explosion. The exhaust from the fiery detonation, seeking the path of least resistance, comes blasting out of each chamber through a constricted nozzle at the base of the rocket. The power of thrust is generated by the purged exhaust, enabling the Zenit rocket to defy the force of gravity and lift itself off the launchpad.
But the final three seconds of countdown are all critical. In those brief few seconds, onboard computer systems quickly monitor the engine start-up, checking propellant mixture, flow rates, ignition temperature, and a host of other mechanical readings affecting engine burn. If a significant deviation is discovered in any of the engine parameters, the automated control system takes over, shutting down the engine and scrubbing the launch. A reinitialization of the entire launch process is then required, which may take upward of five days before another launch can be attempted.
Ling ignored the video screen of the Zenit at the launch tower and instead stared at a computer display of critical measurements as the final seconds of the launch countdown ticked toward zero. At T-1 second, a row of green lights burst onto the screen and Ling allowed himself a slight breath of relief.
“We have main engine thrust up!” he shouted aloud as the display told him the computers were ramping up the rocket's RD-171 engine to maximum launch thrust. Every eye in the room turned to the video screen as the propellant floodgates were opened and the fuel burst through the rocket's engine in a torrent. For a long second, the rocket sat still on the pad as the fiery exhaust burst from its nozzles, the flames licking the water deluge and spraying a thick cloud of white smoke beneath the platform. Then, with a burgeoning burst of power, the Zenit surged up off the pad. The launch tower clamps fell away as the white rocket, erupting with 1.8 million pounds of thrust, climbed up past the tower and into the sky with a blinding glare and deafening roar.
A cheer rang through the launch control center as the engineers watched the Zenit rise successfully off the platform. Ling broke into a broad smile as the rocket climbed higher, grinning good-naturedly at Tongju. Kang's henchman simply nodded back in satisfaction.
At the far side of the bay, the bespectacled engineer who monitored the platform continued to stare mesmerized at the video image of the rocket as it climbed into the crisp blue sky. Oblivious to him was the computation on his computer monitor, which showed that the platform stabilization deviation had continued to rise, creeping past fifteen degrees in the last seconds prior to launch.
Fifteen feet beneath the water's surface, Pitt's ears were bleeding from the acoustical barrage. What started with the sound of a distant freight train had rumbled into the bombardment of a thousand erupting volcanoes as the Zenit's engine reached full thrust. The deafening sound, Pitt knew, was only a warning of the real savagery to come. The building force of the rocket's exhaust was deflected into the flame trench, where thousands of gallons of water dampened the inferno. The blasting force of the exhaust was little repressed, however, gathering into a steaming cloud of fury that proceeded past the deflectors to the open sea below the platform, where it pounded the water like a sledgehammer.
Positioned almost directly beneath the launchpad, the Badger was pummeled like a small toy, surging twenty feet down in a blast of bubbles and vapor. Pitt felt as if he were trapped in a washing machine as the submersible was tossed violently about. The seams of the vessel twisted and groaned from the force of the surge and the interior lights flickered from the shaking. A loose battery pack bounced off Pitt's head, gashing his temple as the submersible nearly turned turtle in the bellowing turbulence. Shaking off the blow, he discovered a new worry when he braced a hand against the bulkhead during a side roll. To his surprise, the bulkhead was searing hot. He quickly pulled his hand away, cursing as he shook it in the air to cool. A sickening thought drew over him as he felt a heavy mist of sweat dripping down his forehead and realized the water sloshing at his feet was rapidly warming. The rocket's exhaust was creating a boiling tempest around him, which might poach him alive before the rocket cleared the platform.
A second, more powerful surge stuck the submersible as the rocket's full thrust came to bear. The force of the current pushed the Badger charging through the water in a contorted angle, nearly on its side. Pitt clung to the controls for balance, unable to see ahead through the turbulent water, which offered no visibility. Had he an inkling where the submersible was headed, he might have braced himself for the impact. But the collision came without warning.
Ripping with the surge like a raft down the Colorado River, the submersible tore head-on into the side of the Odyssey's flooded port pontoon. A metallic clap thundered through the water as the submersible smacked against the immovable hull. Pitt was jerked from the pilot's seat and flung against the forward bulkhead amid a rain of loosened electronic debris as the interior lights fell black and a series of hissing sounds erupted throughout the compartment. A grinding noise told Pitt that the Badger was sliding along the pontoon until another clang erupted and the submersible tilted over to one side and jerked to a sudden stop. As Pitt collected his senses, he realized that the submersible was wedged against the platform hull from the force of the rushing water, perhaps entangled in one of the pontoon's drive propellers. Turned on its side against the huge pontoon, there was no way that Pitt could open the entry hatch, dare he try to flood the interior and escape to the surface. With a sickening awe, he realized that if he wasn't soon baked alive he would face a swift death by drowning trapped inside the leaking submersible.
Six thousand miles away, Kang smiled weakly as he watched a satellite feed of the rocket bursting off the deck of the Odyssey.
“We have opened the genie's bottle,” he said quietly to Kwan, sitting across his desk. “Let us hope he follows his master's wishes.”
Tongju watched intently as the Zenit climbed up past the launch tower with a thundering reverberation that could be felt even inside the bowels of the Koguryo's control center. A lingering applause still rang through the control center as the jubilant launch crew cheered the rocket's ascent. Ling afforded himself a wide smile as the computer display told him that the Zenit's engine was operating at full thrust. He peered at Tongju, who returned the glance by nodding tight-lipped in approval.
“The mission is still far from over,” Ling said, visibly relieved that the rocket was finally under way. But the riskiest phase of the mission was behind them now, he knew. Once the rocket was ignited, he had little control, if any, over the outcome of the mission. With a quiet uneasiness, he settled in as a spectator to monitor the balance of the flight.
