HeliSIM

HeliSIM is the industry standard solution for creating high-fidelity rotary wing flight dynamic simulation. From building and evaluating existing and future rotary wing platforms, simulators, training equipment, and cockpits to developing part-task trainers, HeliSIM is ideal for safety critical simulation applications.

Using HeliSIM, you can:

Conceive and deploy a complete aerodynamic model for the real-time simulation of any rotary wing aircraft without writing a single line of code
Test both aircraft design and aircraft performance under controlled, simulated conditions
Specify subsystems behavior, including flight management systems, autopilot, and flight controls
Easily integrate virtual and/or real hardware devices and user-development simulation modules
Quickly and easily tailor helicopter simulation by entering aerodynamics and environmental parameters into windows and dialog boxes rather than writing software routines to perform the simulation

Current Version

Version 11.0 - New features and enhancements

HeliSIM version 11.0 marks a significant advancement to include a newly redesigned user interface (UI) intended to help customers to get more out of these off-the-shelf simulation software applications. The new user interface will reduce customers’ total cost of ownership (TCO), increase user productivity, and improve ease of use for developers. Inspired by feedback from Presagis customers and partners, the new UI has been designed to streamline work, improve usability, and increase productivity.

Fresh, New User Interface
Version 11.0 multi-platform UI framework for Windows and Linux offers users a totally new experience resulting in productivity enhancements:

A new UI tailored to specific user roles means aerospace/aircraft modelers, simulation system integrators, and training system integrators can develop in an environment to meet the specific work needs thereby improving their ability to navigate the tool and the development workflow
The visually appealing UI takes advantage of the latest technology to provide easy access to basic features and advanced functions of the tool including online help, embedded graphs, and graphical representations of aircraft systems and subsystems.
Tighter integration with the built-in 3D OTW viewer ensures developers can fly a model within the application for quick and easy validation, testing, and simulation of the aircraft.

New Physics-Based Aircraft Models
The new release of HeliSIM includes new aircraft models to further speed simulation of helicopter dynamics by eliminating the need to develop models from scratch. New HeliSIM models available in version 11.0 include a Tiger attack helicopter.

Interoperability With Industry Standard Terrain Formats
In line with Presagis technology vision, version 11.0 offers standards-based interoperability with terrain formats such as OpenFlight, CDB and MetaFlight. Version 11.0 also includes compatibility with TerraPage.

Support for Latest OS and Related Output Compilers

Windows XP (32 bit)
Windows 7 (64 bit)
Red Hat Linux 5.1 (32 and 64 bit)

Version 6.1 - New features and enhancements

Vega Prime based OTW

New Vega Prime based viewer replaces the existing viewer and provides HeliSIM users with a higher quality 3D OTW than the existing viewer.
New 3D viewer enables the analysis of the airframes developed within HeliSIM, the definition of parameters, and the troubleshooting of operations during development.

Location of profile data defining an aircraft platform can now be configured:

The user can now define the location of where the profile data for HeliSIM is stored on a machine.
Allows support for configuration management of the data associated with an individual project.
All system and subsystem profiles are organized according to the project, eliminating the possibility of assembling an incorrect configuration.

A number of defects have been fixed in this new release

See the release notes for more information

Core Features

Aerodynamics modeling capabilities:

Define each control surface on the aircraft
Specify each control law that converts pilot inputs into control surface deflection
Define the impact of the surface deflection on the aerodynamic coefficients
Specify the installed engine(s)

Simulate a wide variety of helicopters:

Simulate rotary wing aircraft with either rigid or flexible blade models and driven by either turboshaft, advanced turboshaft, or by a user customized performance engine:
- Large transport helicopters
- Single or dual-rotary
- Combat Helicopters
- Remotely Piloted Vehicle / UAVs

HeliSIM simulates the following physics-based models that can be deployed or replaced programmatically to bring realism to your simulation application:
