Overview
The ADPATS dummies are hybrid manikins using features of the ADAM and JPATS dummies. They were developed in 1999 to support the Japanese ACES II CMP efforts. These dummies were used to evaluate the limb restraint systems on the Cooperative Modification Program seats. The dummies have the limb joint range of motion measurement capabilities of the ADAM dummy with the ruggedness and simplicity of the JPATS dummy.
Dummy Use
These dummies are used to test ejection seats in fighter aircraft. They are placed into the ejection seats in the cockpit section of the aircraft which are propelled by rocket sleds to aircraft operational speeds. The seats with the dummies are ejected to simulate actual operating conditions including the rocket powered ejection, man-seat separation, and parachute descent. Transducer readings on accelerations, forces, moments, and limb positions are recorded in the onboard data acquisition system. The data is used to analyze effects of the ejection on the occupant and hence survival capability of the system during a live ejection.
Dummy Design
- JPATS designed spine box that allows for self contained 64-Channel on-board data acquisition system-ODAS
- Automotive pedestrian type lumbar spine with vertical response and simplified construction.
- Automotive type force and measurement capabilities
- ADAM ejection seat dummy joint ranges of motion
- ADAM joint soft stops to simulate human joint actual motion ranges and resistance
Description & Construction
The heads are made of vinyl skin over aluminum skulls with removable caps and cap skins to give access to a force and moment transducer and linear accelerometers. The large ADPATS head is built from a Hybrid II casting modified to accept a lower neck transducer. The small ADPATS head is based on a VIP skull modified for the transducer.
The necks are large male and small female Hybrid III—rubber flexible elements bonded between aluminum plates to give biodynamic flexion and extension response.
The neck brackets are ADAM dummy designs with a jack screw to set the neck angle.
The ADAM type shoulder assemblies, covered with removable vinyl caps, have dual yokes to accommodate all ranges of motion. Rings limit the motion with soft stops to the anatomical values. 5 joint position transducers may be mounted in each shoulder-left and right.
The thorax follows the JPATS design with a welded spine box having a removable cover and open side for housing an On-Board Data Acquisition System. The ribs, bib and rib stiffeners follow H3-95 automotive designs. Three angular rate sensors mount on the base of the spine box.
The lumbar spine is a rubber cylinder following aerospace dummy practice. This is a simplification of the ADAM design. Responses to vertical axis loading are similar.
The pelvis follows ADAM design, a sit stand configuration. The buttocks are removable. Position transducers may be mounted in the hips. A linear accelerometer may also be mounted.
The legs are of the ADAM design. The upper legs and lower legs are shaft and tube construction mounting an axial position transducer in each location. The knee angle and ankle angles may also be measured.
The arms follow ADAM design. The upper arms and lower arms are shaft and tube construction mounting an axial position transducer in each location. Elbow and ankle angles may also be measured.
Shaft lengths were modified where necessary to meet the dummy dimensional specifications. The Large ADPATS uses high tensile stainless steel for the limb bones whereas aluminum was used for the Small ADPATS limbs. This is to lower the weight of the Small ADPATS.
Upper and lower leg and upper and lower arm skins are vinyl filled with urethane foam. They are removable from the bones. The hands and feet are solid vinyl with metal inserts.
Calibration
The following measurements are performed on each dummy:
- Weight and CG of whole dummy
- External Dimensions
- Segment weights
- Neck flexion and extension test
- Joint angles electrical and mechanical
Product Verification
Humanetics manufacturing and inspection procedures result in high quality machined and molded parts. Procedures include certification of materials, verification of dimensions, and inspection of overall appearance of finished components
