InView Unmanned Aircraft System

The "InView Unmanned Aircraft System" is an Unmanned aerial vehicle that has been developed by Barnard Microsystems Limited in the United Kingdom specifically for use in scientific, commercial and state applications. The design focus was on safety, automation and modularity.

Introduction

The InView Unmanned Aircraft System was developed in 2010 by Barnard Microsystems Limited for use in scientific, commercial and state applications. The InView is a twin engined unmanned aircraft with a "dry" (no fuel on board) weight of just under 20 kg. The twin engine configuration was selected to enable the InView to fly on one engine, should problems be experienced in the other gasoline powered four stroke engine. The relatively light weight of this 4m wingspan aircraft and use of composite materials were design goals to reduce the amount of crash damage to a structure, such as an oil or gas pipeline.

The distinctive twin boom configuration was used to keep aircraft weight down and ensure the center of gravity of the aircraft was in the desired location: a few inches back from the wing leading edge.

The InView is modular in construction to enable it to be transported in a small van. The modular construction brings with it other benefits:

  • modules can be changed in less than 5 minutes to suit a mission
  • a damaged module can readily be replaced
  • particular modules can be replaced as part of a planned maintenance schedule
