美国空海军联合高级教练机训练需求探析

高级教练机是空军强国飞行训练理念的重要体现.本文对美国空军和海军高级训练大纲的科目编排、内容设置、架次分布进行了分析研究,分析结果表明,除了海军舰载战斗机飞行员需要进行岸基着陆训练(FCLP)和舰基上舰资格训练(CQ)之外,空/海两军的熟悉飞行、仪表飞行、导航飞行、编队飞行、作战/战斗飞行等训练科目的内容设置和训练时间基本保持一致,认为美国空军和海军下一代高级教练机可采用“一机两型”发展联合高级教练机来满足其训练需求.     

JPATS救生系统进展

联合初级先进教练系统(JPATS)是美空海军的第一个联手制造飞机的计划。该计划将用100亿美元为美空海军装备850架原型教练机及相应的地面训练系统。 美国空军和海军的现用原型教练机(T-37,T-34)代表的是50年代的技术,并且已服役了29年以上,超出了其使用寿命,因而将被JPATS生产出的飞机所替换。目前所有的工厂皆遵循操作要求联合提要(JSON)生产。怀特航空基地的航空司令部发出咨询要求,收集对教练机设计的意见,以便形成JPATS对教练机设计有更详细要求的文件。 JSON指明了T-37和T-34飞机有很多缺点和不足之处,而主要与乘员安全有关。T-37的缺点是在准备

军事动态

美国取消联合作战飞机项目由于美国空军和海军的联合无人作战飞机系统项目(J—UCAS)被取消,波音和诺斯罗普·格鲁门公司随即暂停了各自即将下线的第一架 X-45C和第一架 X-47B的装配工作。据称,取消 J—UCAS 项目的原因之一是美国空军和海军之间对飞机的发展有较大的分歧,美国空军希望有一种类似 B—2尺寸的无人作战飞机,而海军的要求则很接近 X—45A 的设计。以上两家公司正在等待美国海军出台新的舰载无人作战飞机的项目要求,以便重新调整研制方向,开始新一轮的竞争。而美国空军则

A maintenance-free lead acid battery for inertial navigationsystems aircraft

Historically, aircraft inertial navigation system (INS) batteries have utilized vented nickel-cadmium batteries for emergency DC power. The United States Navy and Air Force developed separate systems during their respective INS developments. The Navy contracted with Litton industries to produce the LTN-72 and Air Force contracted with Delco to produce the Carousel IV INS for the large cargo and specialty aircraft applications, over the years, a total of eight different battery national stock numbers (NSNs) have entered the stock system along with 75 battery spare part NSNs. The standard hardware acquisition and reliability program is working with the Aircraft Battery Group at Naval Surface Warfare Center Crane Division, Naval Air Systems Command (AIR 536), Wright Laboratory, Battelle Memorial Institute, and Concorde Battery Corporation to produce a standard INS battery. This paper discusses the approach taken to determine whether the battery should be replaced and to select the replacement chemistry. The paper also discusses the battery requirements, aircraft that the battery is compatible with, and status of Navy flight evaluation. Projected savings in avoided maintenance in Navy and Air Force INS systems is projected to be $14.7 million per year with a manpower reduction of 153 maintenance personnel. The new INS battery is compatible with commercially sold INS systems which represents 66% of the systems sold

US Air Force EarthRadar for detection and discrimination of buriedunexploded ordnance

The US Air Force EarthRadar system is a multi-purpose sensor designed and constructed using "radar" principles. This technology was originally developed for the US Air Force to detect buried unexploded ordnance (UXO). Bakhtar Associates developed the US Air Force EarthRadar technology under the DoD SBIR program. The system is capable of detecting buried metallic and non-metallic objects, including glass vials. In addition, the manner in which system hardware, signal processing, and the integrated high resolution global positioning system (GPS) are configured makes it ideal for applications such as mapping subsurface geological features, locating cavities and collapse features, and identifying contaminated ground     

History of Time-Frequency Technology

Present-day collision avoidance systems (CAS) of the time-frequency variety employ modes of operation similar to those of airborne equipment which has been operating in military aircraft since 1959. A fleet operational evaluation of these systems began in 1961 in aircraft of U. S. Navy Helicopter Squadron HS-4, based on the aircraft carrier U.S.S. Yorktown. This equipment utilized a local clock in each aircraft, a separate time slot for each aircraft's interrogation signal, air-to-air coarse synchronization of all stations, and sufficient free-drift stability for time slot keeping. Operational use of one-way ranging with elimination of propagation delay offsets, higher clock stability for open-loop time keeping in the SNS-64 ... AN/APN-169 family of systems began in 1964 in U. S. Air Force C-130E turboprop aircraft. In 1965, use of the EROS I collision avoidance system began during flight testing of F-4 Phantom supersonic aircraft.     

Tailoring MIL-STD-461B for Naval Avionics Applications

Naval aviation electronics (Avionics) systems are specified and procured using MIL-STD-461 to set the fundamental EMI requirements. MIL-STD-461 permits and encourages ``tailoring' the EMI specifications for each equipment to the anticipated usage. In this paper, the Naval Avionics Center Staff Engineer for Electromagnetic Effects presents a typical tailored EMI specification as used within the Naval Air Systems Command to procure carrier based aircraft avionics. Included are the rationale for and the explanation of each modification and an estimate of the electromagnetic environment found aboard the US Navy Aircraft carriers.     

On Exploring Method and Software for Evaluating Effectiveness of Military Training Aircraft

The evaluation of training effectiveness (TE) of military training aircraft, though obviously very important, appears to have attracted much less attention than what it deserves in the open literature. This article aims to start from previous studies and explore further. First, TE of military training aircraft is discussed and our ideas for evaluating TE which are expressed mathematically are proposed. Then, using the presented mathematical models, software is developed that takes into consideration the influence of parameters of flight performance and quality on TE. The software's environment is Borland C++ and it sets up the parameters of trainer, training standard databases and training documents; it can analyze and then give the operational cost and cost-effectiveness ratio of military trainer. Finally, the software is utilized to compare the TEs of HAWK and MB339 with that of Chinese Air Force TF-6. The results of comparison show that the TE of TF-6 is the lowest.
