ATI’S MILITARY STANDARD 810G (MIL-STD-810G) TESTING COURSE
The course emphasizes topics you will use immediately. Suppliers to the military services protectively install commercial-off-the-shelf (COTS) equipment in our flight and land vehicles and in shipboard locations where vibration and shock can be severe
This four-day class will provide education in the purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments. Vibration and Shock methods will be covered together and will include an overview of Sine and Random Vibration as well as classical waveform shock testing, drop testing and Shock Response Spectrum Testing. Instrumentation, vibration equipment, control systems and fixture design will be covered. Each climatic test will be discussed individually, focusing on requirements, origination, equipment required, test methodology and understanding of results. Class members will participate in a tour of a lab that daily performs the full spectrum of 810G tests. Class discussion will be supported by projected visuals and video clips. Commencing with a review of basic vibrations, we will explore vibration measurements and analysis. We’ll compare sinusoidal vs. random vibration testing systems, specifications, standards and procedures. We will emphasize vibration and shock test fixture design, fabrication, experimental evaluation and usage. We will study shock measurement, shock response spectrum (SRS) and shock testing. Climatic testing will be looked at in great detail, emphasizing required equipment and instrumentation, correct interpretation of specifications and hints to ensure that the tests are brought to a successful conclusion. We laboratory test the protected equipment (1) to assure twenty years equipment survival and possible combat, also (2) to meet commercial test standards, IEC documents, military standards such as STANAG or MIL-STD-810G, etc. What you will learn: • perform vibration, shock and climatic tests • evaluate and select equipment to perform testing • convert field measured data into a test program, • interpret vibration and shock test requirements and results, • supervise vibration, shock and climatic tests, • specify and experimentally evaluate vibration and shock test fixtures When you visit a test lab or review a test program, you will have a good understanding of the requirements and execution of dynamics and climatics tests and so be able to ask meaningful questions and understand laboratory personnel responses.

Drone Fleets: The Countries That Possess Them And Potential For Robotic Wars

Despite some pretty disturbing news on UAV developments that are coming from China and a group of other countries U.S. remains the global leader in development, production and most importantly successful implementation of unmanned aircraft vehicles or drones.  However, there is a lot of speculation regarding the world’s expanding drone fleets and their potential for […]
Despite some pretty disturbing news on UAV developments that are coming from China and a group of other countries U.S. remains the global leader in development, production and most importantly successful implementation of unmanned aircraft vehicles or drones.  However, there is a lot of speculation regarding the world’s expanding drone fleets and their potential for reducing the threshold for going to war.  Here is a list of known facts regarding this sensitive issue.
  1. USA is the main developer and manufacturer (however not exporter) of UAVs.  Near the top of the line, the Predator B, or MQ9-Reaper, manufactured by General Atomics Aeronautical Systems, costs about $10.5 million. By comparison, a single F-22 fighter jet costs about $150 million.
The new smaller models are currently developed.
  • Raytheon Missile Systems is in process of designing a 13lb Small Tactical Munition to be carried by smaller unmanned aircraft like Shadow, TigerShark, Hunter and Viking. The device is around 24 inches long and 4 inches around.
  • Northrop Grumman has come out with the Viper Strike, a gliding,GPS-aided laser-guided variant of the Northrop Grumman Brilliant Anti-Tank (BAT) munition which originally had a combinationacoustic and IR seeker. The Viper Strike is 36 inches long and only 5.5 inches in diameter.
  • Lockheed Martin has releasedthe Scorpion (21.5 inches in length, and 4.25 inches in diameter),which is adaptable to multiple launch platforms, including manned or unmanned systems.
  1. China is constantly increasing it’s development and production as well as export of drones.  At the most recent Zhuhai air show they revealed WJ-600 drone and than two dozen other Chinese models. Little is known about their actual abilities but the speed at which they have been developed highlights how U.S. military successes with drones have changed strategic thinking worldwide and spurred a global rush for unmanned aircraft.
  2. Israel, the second-largest drone manufacturer after the United States, has flown armed models, but few details are available.
  3. India announced this year that it is developing ones that will fire missiles and fly at 30,000 feet.
  4. Russia has shown models of drones with weapons, but there is little evidence that they are operational.
  5. Pakistan has said it plans to obtain armed drones from China, which has already sold the nation ones for surveillance.
  6. Iran last summer unveiled a drone that Iranian President Mahmoud Ahmadinejad called the “ambassador of death” but whose effectiveness is still unproven, according to military analysts.
China’s drone technology hasn’t reached the world’s first-class level, but the Chinese are catching up quickly. This is something we know for sure.

Question: By the way, when was the last time you updated your current skills or learned new ones? Answer: It could be as easy as taking a short course or two to stay updated in your current field.
If you are in need of more technical training, then boost your career with the knowledge needed to provide better, faster, and cheaper solutions for sophisticated DoD and NASA systems. How many of the following situations apply to you: Don’t have the time for a full semester college course? Is the nearest class clear across town at rush hour? Do your educational needs run more toward “Advanced Topics in Digital Signal Processing” instead of “Introduction to Business”? Do you count decibels (dBs) more often than dollars ($)? Is the radar equation more familiar to you than one for amortized interest rates? You think satellites are sexy, not Lady Gaga? If one or more of situations apply to you, why not take a short course instead? Since 1984, the Applied Technology Institute (ATI) has provided leading-edge public courses and onsite technical training to DoD and NASA personnel, as well as contractors.

  Video Clip: Click to Watch “Soft Skills” May Help You Get or Keep a Job In a 2008 survey of more than 2,000 businesses in the state of Washington, employers said entry-level workers in a variety of professions were lacking in several areas, including problem solving, conflict resolution and critical observation. You’ll likely see these “soft skills” in job descriptions, after demands for technical qualifications. Employment experts agree that tech skills may get you an interview, but these soft skills will get you the job and keep it. Since 1984, ATI has provided leading-edge public courses and onsite technical training to DoD and NASA personnel, as well as contractors. Some of our courses cover these “soft skills” as well. One of these “soft skills” is teamwork. Forming and leading teams is critical to becoming a successful leader. Successful leaders learn good team formation skills teamwork is a keystone of effective projects. Some of our teamwork related courses are summarized below. ATI PROJECT DOMINANCE COURSE This two-day course is designed for engineers, scientists and managers who work in the projects domain on complex systems. Students will learn how to build a cancellation-resistant project, how to form and lead a world-class project team and how to lead the entire effort to a successful conclusion. Cross-discipline and inter-generational techniques are taught and key topics are reinforced with small-team exercises. Attendees are given the Meyers-Briggs© assessment – many discover mismatches in temperament and assignment. All learn how to be much more effective on Project Teams. ATI’S PROJECT MANAGEMENT OVERVIEW AND LEADERSHIP COURSE This class is an introductory class to the Project Management discipline. It includes the basics of Project Management as well as Leadership as it pertains to Project Management. This course is intended for project managers and team leaders who need a good foundation for further study in Project Management. There are no prerequisites for this course. ATI’S FUNDAMENTALS OF PROJECT MANAGEMENT COURSE Today’s complex systems present difficult challenges to develop. From military systems to aircraft to environmental and electronic control systems, development teams must face the challenges with an arsenal of proven methods. Individual systems are more complex, and systems operate in much closer relationship, requiring a system-of-systems approach to the overall design. This three-day workshop presents the fundamentals of project management approach to solving complex problems. What you will learn: • How to prepare a sound plan for your project and maximize your probability of success • How to achieve Buy-In from the people who will perform the work on the project • How to deal with conflict and also to use it to the advantage of your project • Techniques for monitoring and controlling the outcome of your project • Effective approaches to managing multiple projects Course Outline, Samplers, and Notes Determine for yourself the value of our courses before you sign up.
