Aerospace Blockset 3.4

Simulating Aerospace Vehicle Components

The aerospace vehicle component block libraries in Aerospace Blockset™ let you design and test a complete vehicle simulation in a single model. For example, you can perform analyses and trade-off studies to understand system behavior under a variety of environmental conditions and parameter constraints and use prebuilt guidance, navigation, and control (GNC) components to verify the response of a radar system before full system specification.

Aerospace Blockset specialized blocks for modeling, integrating, and simulating aerospace systems using mathematical representations from references and first principles. Click on image to see enlarged view.

The GNC library includes guidance blocks for calculating the range between two crafts given their respective positions. Navigation blocks for modeling a three-axis accelerometer, a gyroscope, and an inertial measurement unit are also included. Multiple controller forms let you investigate the effects of implementation architecture on your design. Forms include predefined state-space controller blocks for one-, two-, and three-dimensional gain scheduling; linear interpolation; observer- and self-conditioned forms; and one-, two-, and three-dimensional matrix interpolation.

The Propulsion library includes a turbofan engine system block that implements a first-order representation of the engine and the controller. It computes the thrust and fuel flow at a specific throttle position, Mach number, and altitude.

The Actuators library includes component blocks for simulating second-order linear and nonlinear actuators.

The Mass Properties library includes blocks for estimating inertia tensor and symmetric inertia tensor and for calculating moments about center of gravity due to forces.
