Hardware-in-the-Loop (HIL) Simulation

Cost, availability, and safety make testing aerospace and defense systems in real-world settings impractical. Hardware-in-the-loop (HIL) simulation can virtually test embedded technologies like single-board computers and electronic chassis.

Hardware-in-the-loop (HIL) simulation enables engineers to be proactive and test specific embedded technologies like single-board computers, and electronic chassis and enclosures in a virtual environment.

NI Expertise Overview

It takes time and money to test and repair avionics, flight control, and intelligence, surveillance, and reconnaissance (ISR) systems in aircraft and commercial space transportation. To reduce costs and ensure system reliability, engineers use HIL simulation to test embedded systems virtually before running higher risk, more expensive, and time-consuming real-world tests. This helps to ensure reliability and meet time-to-market requirements even as systems grow more complex. NI offers flexible software and modular, commercial-off-the-shelf hardware platforms that support a range of tests from single systems to iron birds and systems integration labs. With the flexibility and breadth of the platform, you can use the same hardware and software for not only advanced RF applications, signal intelligence, and software defined radio but also avionics systems and flight controllers.
