Parachute (Torso Dummy)
- Humanetics - 131-001
The Parachute Dummy (Torso dummy) has evolved into its present form primarily on the basis of continued use by United States Government parachute test groups. The present version is the most rugged dummy ever developed - it is capable of withstanding repeated free falls with minimal or no damage.
The torso corresponds to a 95th-percentile male, 6 feet 1 inch tall. The torso weighs 188 + 2 lbs. The normal weight of a young male of this stature is 211lbs. Hence, there is a nominal 23-lb weight allowance for instrumentation. The torso structure is a steel weldment, terminating at the base of the neck and at the shoulders in steel flanges which mate with manganese bronze caps.
The structure is machined to receive instrumentation packages, which extend into the torso. The torso is terminated in a de-mountable steel 'kick-plate,' providing access to the stub-leg instrumentation cavities.
Two chest cavities are provided, each with its own flesh covering, for installation of accelerometers or other instrumentation and for junction strips and wiring.
The flesh is molded of a very tough vinyl about the torso structure. Although this dummy, when instrumented, has a weight corresponding to a man 6-feet 1-inch tall, it will reach a higher terminal velocity due to the absence of arms and legs which produces lower drag. It will also rotate faster than a human due to lack of human energy-absorption, lower moment of inertia, and lack of dynamic response.
The dummy is furnished with all tools needed for assembly and disassembly.
The 131-001 Parachute Dummy is a modification of the previous PA-001 parachute dummy design, and has become the standard parachute dummy supplied by Humanetics.
The weight, external dimensions and general design of this dummy are the same as those of the PA-001 parachute dummy. The color of the vinyl body is spectral white, which sharpens the contrast of the dummy on event films.
Provision was made for slightly larger instrumentation cavities in the torso to accommodate modern battery packs with foam padding and for enlarged instrumentation space. Internal ducting between the instrumentation cavities and the neck, arm, leg, and body sections was enlarged and augmented to facilitate wiring.
