Aerial Refueling

SDI has a history of supporting the US Navy in aerial refueling modeling, simulation, design, analysis, and testing since 2009. 
 
Our aerial refueling involvement has included probe design modifications, hose simulation and design optimization and component analysis, including engagement mechanism, drum and reeling mechanism, and the MA-3 fuel valve. 
 
The company is currently developing new design options for a modern, structurally optimized hose that will also improve stowage capacity to allow for longer hoses or lower weight refueling pods.

Our Software Solution

ARES software logo

SDI Engineering has developed an aerial refueling modeling and simulation tool using multi-body dynamics methods in MATLAB, Simulink, and Simscape Multibody.   

ARES can be used in the detailed analysis of:

  • Aerial refueling operations for new technologies

  • Incident investigations

  • Evaluations of flight control or maneuver strategies

  • Probe loads predictive analysis for design, flight testing, and certification

ARES is the ideal tool in order to better understand the dynamics of the hose and drogue, reeling mechanism, probe, and the resulting loads during aerial refueling operations.

Capabilities

  • Lumped-parameter models of the hose, drogue and probe allow simulation of structural behavior including temperature dependent nonlinear stiffness and damping

  • Structural models can be modified to simulate refueling events using flying boom and boom-to-drogue adapters

  • Hose aerodynamic model included to capture aeroelastic behavior during hose whip events

  • Hydraulic reeling mechanism model allows regulation of hose tension during aerial refueling

  • Probe-drogue engagement model allows simulation of all phases of aerial refueling
