System Analysis

Multiple stress and structural simulation capabilities are an integral part of Airborne Systems engineering services.

Parachute Trajectory Modeling and Simulation

Extensive analysis capability exists within Airborne Systems trajectory modeling and simulation.

Airborne Systems primary parachute deployment, inflation and trajectory application, Decelerator Dynamics (DCLDYN) has its original algorithm roots dating to the Apollo program. Significant capabilities and validation have been added over the years. Airborne Systems parachute trajectory simulation includes all of the higher order terms of parachute deployment and inflation including:

Time dependent parachute drag area, including highly nonlinear responses
Parachute mass growth during inflation
High order cargo body aerodynamics
A variant that assesses vehicle reorientation events

Modeling of aircraft floor for aerial delivery application, including ramp tip-off simulation

Inputs for variable atmospheres, Earth or off-planet

Wind profiles

Temperature/density variations

Ejection seat modeling with crew acceleration exposure computations

Deployment forces such as mortar or tractor rocket

Landing brake parachute modeling for the aircraft

High quality parachute simulation for coupling with a customer vehicle

Development of a trajectory Monte Carlo simulation, implemented as scripts, which provide outer loop execution of the basic DCLDYN application, this capability includes:

Primary model inputs which the user can vary, such as:

Parachute drag area
Inflation characteristics
Vehicle aerodynamics
Deployment initial conditions such as airspeed and position

Flight atmosphere conditions

Prevailing winds
Density profile
