Tiềm lực quân sự Hoa Kỳ - Phần 3

Tội nghiệp, Quân Nga trang bị UAV đến từng tiểu đội nhưng cả mặt trận Gru thì không.
Tội nghiệp chắc cả tiểu đội xúm nhau khiên con Tipchak không biết chấm toạ độ.
Tội nghiệp không có con nào khoe tối ngày rống con Đồ Zốt 600 còn chưa cất cánh bao giờ .
Thiệt là tội nghiệp . Còn khoe FCS Nga nữa nhưng không biết có hiểu FCS là gì không nữa.

Một trong những con được che dấu rất kỹ không rõ hiện nay ra sao. Có lời đồn là từng dùng hồi đánh Iraq 2003. UAV bí mật?

Vâng, kính thưa các quí dị khán giả đã no mắt với các hình dáng UAV tân kỳ xứng đáng bay trong phim X-men hay Star War thì xin hãy trờ về thực tại để xem quân đội Mỹ đang dùng nhưng con UAV gì và các nhà thầu thực sự chào hàng cái gì:
Đây Scan Eagle:

Đây là các nhà thầu đang chào cho gói UAV cấp battalion:
"Asked to clarify that range of requirements, Flach says the Mk 4.7 will meet all of the STUAS/Tier II contract''''''''s threshold requirements, but not all of the objective requirements.
AAI originally planned to offer the 56.7kg Aerosonde Mk 5 for STUAS/Tier II. However, the company''''''''s database of requirements research suggested a smaller aircraft was a better fit for the job, Flach says. "
Trông ra sao nhỉ:

Bí bí quá-Mĩ dùng loại khác rồi
The U.S. Air Force''s Hunter-Killer program is a series of five tactical unmanned combat air vehicles, one of which will be selected for production in 2007 or later.
The MQ-9 Reaper won the project and is now being deployed in Afghanistan.

ON PROGRESS OF UNMANNED AIRCRAFT IN TUPOLEV DESIGN BUREAU
At the end of 1957 TUPOLEV Design Bureau appointed a group of specialists to start activities on unmanned air vehicle. The activities were headed by Alexey A.Tupolev. The work started without formal orders making no special publicity. It was not a passion with popular subject ?" from the very beginning the new tenor of advanced aviation was treated seriously. First of all it can be explained by increased requirements to aviation development in accordance with state-of ?"the-art level of that times. Certainly there was a rational attitude to application of aircraft capable to operate without pilot saving his life. Absence of the pilot in an air vehicle immediately puts much more severe requirements *****ch aircraft characteristics as G-force, altitude, vibration, temperature and some others.



To-day it does not matter how the DB started working on the new trend of aviation ?" weather it was done under Government Decree or in Andrey Tupolev initiative supported by the higher authorities. By the way, at that time the DB performed many investigations in various trends of aviation. Andrey Tupolev appealed to Commandment of Army and to Government with issues on many of these investigations. It was normal way of working at that time. In 1957-1958 Alexey A.Tupollev together with his assistant Victor Saharov elaborated a structure of new division, gathered the backbone of the collective, defined key trend of work. And the work started in full swing. The core of the team was composed of V.Blizniuk, Y.Orlov, N.Kozlov, V.Andreev, A. Davtian, A.Kochrgin, G.Cheriomuhin, A.Kaandalov, S.Svirskiy, B.Saharov, B.Stoma, V.Ryabenko, G.Polezhaev, Y.Shumilov, G.Gofbaauer, B.Grozdov, L.Lanovskiy, V.Kulinskiy. All of them were emplyees of our Design Bureau and rather young people. Said division was a part of the DB and was designated by index ?oK?.

The first task of said new collective was building of unmanned strike aircraft of strategic purpose (TU-121, ?oC? aircraft).
This was unusual work for the DB. It was not because of complexity of the air vehicle itself having rather high technical characteristics : booster-rocket launching at takeoff equal to 35 t, cruise flight at the speed up to 2700 km/h at the altitude of 22000 m and range of 4000 km. When work started the most unusual were the requirements to combat application of the air vehicle and operation. Complex composed of several air vehicles and aids of ground support had to be completely autonomous and capable to leave their bases independently, to operate from unprepared fields maintaining combat con***ion. It was necessary to solve problems of no aviation nature which were not considered in the DB previously. Management of the division had to arrange new services, to establish business links with non-aviation organizations. Designing of the air vehicle itself also raised a number of technical questions. Such as selection and test of unusual aerodynamic layout, heat demand, especially of radio-equipment, development of autopilot system that provided both stabilization of the air vehicle and capability to fly along preprogrammable path. It was necessary to build multimode short service life turbojet engine that operates at reheat power, to design air intake that provides engine operation both under sub-sonic and supersonic con***ions. There also were questions regarding fuel system functioning in view of in-flight fuel heating and some other problems. Airframe skin temperature in flight was equal to 100-120oC. Total start thrust is 160 tf at operating boosters and reheat power main turbojet engine. So there were many issues difficult from technical point of view. And the collective began to solve them.
It should be noted that Alexey A.Tupolev showed himself worth as manager of the project. He always showed high capacity for work. He worked 10-12 hours a day being in contact with specialists substantially all the time.

Works on large-range unmanned strike aircraft which started in 1958 were stopped in 1960 defining a basis for activities on unmanned reconnaissance aircraft ?oYastreb?-DBR-1. Said works were successfully completed in 1964. From 1965 DBR-1 complex entered serial production. The aircraft had unique characteristics for that time. It was completely autonomous for combat missions and data acquisition and processing.
?oYastreb? reconnaissance aircraft had flight speed of 2700 km/h, flight range ?" abut 4000 km and flight altitude ?" 19-22 km. From said altitude it was possible to recognize railway sleepers. It was the real break-through in various trends of aviation science. To perform photo-reconnaissance long-focus aerial camera and radio-reconnaissance station were built for the first time for in-flight record of all data received from military radio-emission sources. ...................
