Combustion by-products on F-4 drogue parachutes. Final report

Concerns of F-4 drogue parachute packers concerning cracking and peeling dry skin led to analysis of the parachutes for polynuclear aromatic hydrocarbons (PAH). F-4 drogue parachutes with varying numbers of deployments were analyzed for PAH. Results show a linear increase of PAH concentration with increasing deployments. Protective measures are suggested.
