New Flying Leopard using 3D digital design and the international advanced level
Data for: Air Force equipment, new Flying Leopard fighter
2011 年 1 14 January, China Aviation Industry Corporation First Aircraft Design Institute of red chief architect Don ushered in a long life and a new starting point: as JH-seven A (the new “Flying Leopard”), the first aircraft to complete the project, he received the National Science and Technology Progress Award. New “Flying Leopard” aircraft, not only my empty while the Navy selected the only protection space “artifacts”, and my fighter’s performance and enhance the combat effectiveness of a whole generation!
youngest chief architect
1982, the long red Tang graduated from Northwestern University, was assigned to the First Aircraft Institute of Strength of ventricular fibrillation vibration professional group work.
time, the unit is only one computer, you need to use 24-hour shifts. Red is always the young Don long night shifts, night work. At that time, he not only read many books, they do a lot of books, the accumulation of knowledge.
1988 years, an aircraft equipped with flight control system, doing ground tests, sharp horizontal tail buffeting. Was already in the Beijing Aerospace University Master Tang long red, and guidance counselor after painstaking study, the use of the installation of “trap pieces of filter” approach to solve this problem.
Since then, his experience in the domestic case of no reference, in aircraft design stage servo chatter proved the existence of potential hazards to aircraft, developed a ground test match program, and they are being tackled aircraft vibration , vertical tail and rudder flutter testing and flight test and other problems. Among them, the “flexibility and ground test aircraft servo technology”, “double-objective optimization of active flutter suppression control technology” were given ministerial level scientific and technological progress prize and third prize. In addition, Don has created a long red country on the whole plane stress solution for a precedent. These achievements, earned him industry recognition of the authority.
Don just four long red early twenties to become the new “Flying Leopard” the chief architect of the aircraft, the aviation industry was also the youngest chief architect of the system.
dare to break the routine
long red Tang and his team decided to break the routine, a breakthrough in the design means that using the most advanced aircraft design software full machine three-dimensional digital design. Before, this design only a small part in the country on the tried, the design on the computer now more than fifty thousand aircraft parts, a dozen systems, and digital assembly for full machine. Moreover, this version of the software is the first time in the world.
the face of concerns from all sides, long red Tang professional staff, the formation of research groups, with everyone fighting, hungry, eating a few mouthfuls of biscuit, sleepy children take turns to take a nap on the couch … … 2000 September 26, through the efforts of Don and his team long red the first time using the latest version of CATIA V5 software to design the first electronic prototype machine-wide rack, the first time in the domestic development of the aircraft and electronic pre-assembled three-dimensional design, from traditional design one step to the international level. Shocked the international aviation community, the Chinese people in just one year to achieve a three to five years in foreign demand to achieve the technological revolution.
the national “863″ Achievements Over 15 Years on the results that some of the Academy of thumbs: This is the real high-tech! The CATIA software, co-founder of the French Dassault’s vice chairman Bernard that after the fax sent to Tang in a long red notice any exclamation mark with three expressed surprise and congratulations.
the whole machine to make 3D design technology originally planned two and a half of the aircraft design cycle for the year to enable the engineering change order from the regular six-seven thousand down to a thousand sheets, significant cost savings. Since then, the rapid spread of the technology in the industry, so that the design of China’s aviation industry means full integration with the world advanced level. The results also won the 2003 National Science and Technology Progress Award.
“rigorous” + “hard work”
fire control system integrated avionics is the new “Flying Leopard” developed by the key. Figuratively speaking, this system is the aircraft’s “head” command of the aircraft’s “nervous system”, a direct relationship between overall performance and combat aircraft! A flying hospital did not do before the fire control system integrated avionics master the overall design and software development, even the one God had prepared the statement did not! At that time, information is also very rare.
as chief architect, Don oversaw the formulation of long-red system design and configuration program, a bold decision with hierarchical, modular advanced configuration options. In system development and debugging, he went to the relevant auxiliary plant in-depth research, and designers together to crack problems.
those days, Tang long red room and board at the scene, to work night and day. Yellow face boil, boil red eyes, teeth still persisted. High work load, make him feel old in the office when the swelling of the feet, had to bring a pair of shoes from home to office to put on … …
at work, he is notoriously rigorous . “We want to put the safety of aircraft into space, we draw every line, every one out of maps, each a technical report, provided each curve, each data must be well-founded, that passed the from the scrutiny and the test of God. “Tang told the people around often long red: aviation products is no small matter, each piece is attached to ten million, we must dedicate themselves,” treading on thin ice, immersive an abyss “and seriously dry.
present, this fully developed by our own fire control system integrated avionics, proven performance, reliability and stability, and installed with our country in the third generation of this technology to meet international standards.
“to effectively pool our wisdom,”
in a long red under the leadership of Don, “a flying hospital” with more than two years will complete the conventional design requires four years to complete the workload. New “Flying Leopard” aircraft from the model project to the troops, only a short period of five set spring, creating a miracle in the history of the aviation industry.
new “Flying Leopard” The successful development of the aircraft, indicates that China has a type with completely independent intellectual property rights, with three-dimensional precision air strike capability of the main aircraft types, China has independently developed the ability to achieve the new fighter-bomber yet another new leap forward!
in the “Peace Mission 2007″ joint military exercise in the participating countries to the officers and men of the new “Flying Leopard” and spoke highly of the performance. Russian pilots into the cockpit exclaimed: “I did not think China can build such a good plane!”
Tang has long red does not meet the achievements, but to lead his team developed a ground-breaking multi-type The aircraft, which he also won a key honor: In 2001 a special government allowance from the State Council in 2006, won the “National Labor Medal” in 2010, is awarded the “National Advanced Worker” ” outstanding scientific and technological workers, “the two awards.
aviation experts as a scholar, Don always said that success in a long red key on their own team. He often talk in this matter: the new “Flying Leopard” developed the most tense, often until midnight or the hospital lights.
“It is because of the development efforts across tens of thousands of cadres and workers, have today’s achievements, I just put all the wisdom to effectively gather together.” He said, “can bring together the wisdom of , the easy to use, effective aircraft dry out, is my greatest wish. “
2010, the national model workers and advanced workers in the forum, as the sole representative of science and technology front, he told Party and state leaders reported on their work and determination: “the brave, innovative beyond, for the modernization of national defense and make new contributions!” In the same year, developed by him as the chief architect of the new “Flying Leopard” aircraft live up to expectations , won the Grand Prize of national defense science and technology achievements. He is to “‘Made in China’ aircraft leader” renowned Don long red inside and outside the industry.
