Unmanned Systems
Unmanned Systems How many hours can you stay awake? How far can you see? How well can you see at night? How long can you survive in the vacuum of space? How long can you go without drinking or eating? How long can you stay sitting in a tight space? How long can you survive in microgravity? What limitations affect human-operated systems? What is the value of human life?
Unmanned Systems A system without a human on-board Human factor is reduced System operations are controlled by a remote human or processor capable of interpreting inputs and establishing proper outputs
Unmanned System Environments Air Unmanned Air Vehicles (UAV) Ground Unmanned Ground Vehicles (UGV) Maritime Unmanned Maritime Systems (UMS)
Unmanned System Design Components Operational Environment and Task Sensing Communication Information Processing Energy Source Energy Transfer
Unmanned Systems: New Age or Old? 1888 Louis Brennan demonstrated a wireguided torpedo 1898 Tesla introduced Telautomaton, a four foot long boat that could start, stop, and turn using radio frequencies Why was the first unmanned system a maritime system? naval warfare was a significant focus for military strategists at the time.
Telautomaton Success What concepts did Tesla need to understand in order to create his unmanned maritime system? Operational Environment and Task Buoyancy, materials, and structures Laws of motion – Start, stop, turn on command
Telautomaton Success Energy Source Electricity – Battery Energy Transfer Electrical Mechanical – Electric motor, energy transfer to propeller, and laws of motion
Telautomation Success Communication Radio frequency transmission and receiving Information Processing Switches triggered by direct communication
Unmanned Aircraft System Design When was the first unmanned aircraft system designed? 1915 What system design components limited the success of early unmanned aircraft designs? ALL – Due to a lack of technology
Unmanned Aircraft System Design What operational environment and task limitations existed? Flight concepts Automatic stabilization Autonomous navigation How are these limitations overcome today?
Unmanned Aircraft System Design What energy source limitations existed? Electrical batteries Petroleum fuel What energy transfer limitations existed? Pneumatic parts from organs operated mechanical parts High-weight, low-power engines How are these limitations overcome today?
Unmanned Aircraft System Design What communication limitations existed? Radio frequency transmission and receiving What information processing limitations existed? Processing had to be performed by the operator How are these limitations overcome today?
Today’s Unmanned Systems Technological advancements push unmanned system developments Versatile, Adaptable, Persistent Civil and Commercial Reconnaissance Combat Logistics Research and Development Target and Decoy Exploration
