Chinese Liaoning Carrier has teething problems

BEIJING — Two pilots in a squadron conducting
fighter jet take-off and landing tests for China's lone aircraft carrier
[Liaoning] were killed during trials, state media reported, offering a rare
glimpse into the secretive project. The revelation of the deaths
came in a report last week on the signing of an order of commendation
for the crew of China's first carrier-based jet fighter, the J-15. "Two
test pilots of the squadron sacrificed their lives during the tests,"
the official Xinhua news agency reported on August 27.

on at least one occasion during recent sea trials, Liaoning appeared
to suffer a steam explosion which temporarily knocked out the carrier’s
electrical power system. The failure, reported by Chinese media site
Sina.com, resulting from a leak in “the machine oven compartment to the water pipes.”

Would an engineering casualty represent a setback unseen in the annals
of naval history? Hardly. All sea services have been there, done that,
and will likely find themselves there again. It’s doubtful such travails
will induce PLA Navy officials to overreact, demoting Liaoning
from whatever plans they have in mind for her. China’s first aircraft
carrier is probably destined to serve as a training platform in any
event — a ship used to groom China’s first generation of naval aviators,
flight-deck crewmen, and air-group commanders. She will remain such
despite minor hardware problems belowdecks.
Aircraft Carrier Liaoning - The Propulsion Problem

Evidence suggested that as of 2013 AVIC’s aviation gas turbine engine
makers were still having trouble maintaining consistent quality control
as they scaled up production of the developed engines, causing problems
with reliability. That is where overseas suppliers play a useful role to
reduce risk, match complementary expertise, and enhance financing and
market access. As is well known, China is deficient in marine propulsion
technology, and has not produced significant steam turbine or gas
turbine marine propulsion plants. Only a few PLAN warships are equipped
with such propulsion plants, which are standard in navies around the
world, and the few Chinese installations involve plants of foreign
manufacture. China's commercial and military surface vessels are
uniformly outfitted with marine diesel engines, many of foreign design
built under license.
Instead, it seems that marine gas turbine engines from Ukraine were
fitted. The Ukrainian company Gas Turbine Research & Production Complex Zorya-Mashproekt is one of the world leaders in gas turbine
construction. The company designs and constructs gas turbines for
sea-going merchant fleet and navy, for power industry and gas transport
mains opening up new possibilities for the world. Company products are
provided to Russia, Byelorussia, India, China, Vietnam, Singapore, South
Korea and other countries. The company's largest engine, the Gas
turbine engine UGT 25000, is a three-shaft gas turbine comprising
two-spool gas generator and free power turbine. It has a rated power of
26,700, or about 36,000 shp. Six such engines would be more than
adequate to power the ex-Varyag

Chinese military today dismissed reports of an explosion on board its lone aircraft carrier, Liaoning which is currently undergoing advanced trials. Reports in foreign media of an explosion on board the aircraft carrier "did not conform with the facts", Defense Ministry spokesman Yang Yujun said in a press conference today.
