Safety Analysis For Evaluating (SAFE) sUAS

(Phase I: Jun 2016 - Dec 2016, Phase II: Jun 2017 - May 2019)

Introduction

  • No standard safety tool for sUASs exists today

  • Safety procedures for sUAS will require ability to simulate sUAS trajectories with high level of precision

  • SAFE sUAS Approach

    • Develop high fidelity sUAS trajectory model (sUTG by IAI) informed by high fidelity simulations and flight test for variety of sUASs

    • Use these models as inputs to existing UAS safety models

Small UAS in the NAS OV1 (UTM Project)

“Currently, there is no established infrastructure to enable and safely manage the widespread use of low-altitude airspace and UAS operations, regardless of the type of UAS”

sUAS Trajectory Generator (sUTG) Overview

  • UAS Flight Demand

    • Flight plan-like information for each sUAS flight

    • Sample flight plans were developed for this briefing

  • Rotorcraft Performance Database (RPD) <= Our Part

    • Aircraft performance under different mission segment and altitude combinations

  • sUAS Trajectory Generator (sUTG)

    • 3 DOF trajectory model that computes flight trajectories at 500 millisecond interval

Rotorcraft Performance Database (RPD) Development

  • 6-DOF Model

    • Develop the equations of motion and obtain the parameters of specific sUAS models through tests

  • 6-DOF Mission Simulations

    • Hardware in-the-loop (HIL) simulation and/or flight tests

    • Refinement Loop: To develop the 6-DOF model

    • Production Loop: To populate RPD
