| Abstract: |
Towing of a Magnetic Anomaly Detection (MAD) system is an important aspect of rotorcraft
maritime operation in support of Anti-Submarine Warfare (ASW). The vibratory rotary wing
platform combined with the long and flexible towing cable, the low mass ratio of the
towed body to the total mass (the sum of the tow body and the towing aircraft), and the
rotor downwash impingement on the towed body during deployment presents a challenging
task for integration of a modern towed MAD system on USN airborne ASW platforms. Phase I
of the proposed research emphasizes towing simulation methodology research and
development. Phase I will also carry out a full flight simulation with a towed body to
demonstrate the feasibility of the proposed simulation method. Overall, Phase I will
accomplish (1) the development of a high fidelity aircraft simulation model for
accurately capturing both the steady state performance and the vibratory characteristics
of the towing operation; (2) the development of a state-of-the-art model for the
interference of the towing aircraft rotor wake on the towed body; (3) the development of
high fidelity dynamics and aerodynamics modelling of the towing system including the
towing cable, the towed body, and the cable attachment device; (4) the performance of a
full flight simulation with the integrated towing aircraft and towing system; (5) the
performance of initial parametric studies to investigate the towed body aerodynamic and
dynamic characteristics including the effects of body geometry, size, mass/inertia/CG,
aerodynamic stabilizing surfaces, etc. |
| Benefits: |
The high fidelity simulation capability developed from this STTR will directly address
the needs in supporting both towing and sling load operations that are widely used in
search and rescue, cargo transportation, and construction (power lines, high-rise
buildings, bridges, etc.). Potential benefits include applications in the DoD, other
government agencies, and the private sector. This STTR has a high potential to result
in multiple avenues of revenue from commercialization that will support advanced future
vertical lift design, existing aircraft upgrade, and aircraft sling loads/towing
operations for enhanced flight safety and efficiency. |
