Titanium applications in our military aircraft engines

With WP-13 series engines did not count stereotypes, engine production jump yields also increased, to 1990 WP a J3 series engine with titanium has more than lOGt, titanium alloy sheet plant in the company amounted to eliminate the sale of more than 18 million yuan. Therefore, WP-13 series engines bulk titanium for our dirty air engine has accumulated flying experience, and promote China's aviation titanium.
Aerospace from the early 1970s on the aeroengine conducted pre-research work Titanium application, after 16 years of hard work to make TCl, TC2A, TC4, TCS, TC11, TA6, TA7, ZT4, ZT3 total of nine brands the elimination of the alloy used WP-7B (BM), the WP-13 and four modified engines, so that our aviation engine into the production phase of titanium and has effect subject to a variety of night flight test.
To meet the needs Jian Qi an M-type aircraft, for WP-7B engine improvements designed to ensure that the aircraft balance, resulting in the afterburner section, weight 17kg. In addition to weight reduction measures taken by the structure did not count, but also the use of grade 1 titanium sheet and titanium alloys replace some stainless knot 抅 titanium, which is an important means to reduce the weight of the engine. Therefore, in the WP-tBcbm engine afterburner parts department with a total of 22 four grades of titanium, titanium single quota for 59.47kg.
The launch ridiculed in 1982 by the Ministry of Aviation Industry technical appraisal and loquat into mass production, some of which were exported. As of 1990, the total production of the engine hundreds, titanium has more than 30t, with sales of 5.4 million yuan titanium plant. Volume applications of titanium alloys for aircraft engine company exports worth more than $ two 丨 B. It is worth noting that the actuator cylinder engine afterburner ashamed TC6 alloy by using isothermal forging of thin-walled hollow forgings, is the earliest use of aero engine isothermal forging of large bearing parts for our titanium alloys in aircraft engines application accumulated practical experience. The machine has developed five types of engines, using nine grades of titanium seamless pipe, titanium alloys used in China is currently the most burning aircraft. From the use of titanium level analysis, TCll (BT9), ZT3 is heat resistant alloy 500 long-term use of it, up to the international level in the early 1980s. From the engine with titanium content 'points off, Titanium Pan zero weight of the total weight accounted for 14% of the engine, the engine is a single titanium quotas were 855kg and 1055kg, is China's current production of aviation engines loquat amount up to the amount of titanium models .
