| Title: | Human Factors Of Emergency Evacuation | ||||
|---|---|---|---|---|---|
| Author: | Stanley Mohler | ||||
| Abstract: | More than one hundred years ago Lord Tennyson prophesied �Saw the heavens filled with commerce, argosies of magic sails, pilots in the purple twilight dropping with costly Bales. He possibly did not foresee certain complications associated with such aerial commerce, particularly the �dropping down� with more than the usual drop force. The �costly bales� which comprise the topic of this paper, are the soft protoplasmic masses encased within aircraft. The aim of emergency evacuation is to get these soft protoplasmic masses from the interior of a distressed aircraft to the exterior, without irreversible damage. This paper will focus on what we term the human factor in emergency evacuation. Anything, which unduly impedes the processes of emergency evacuation, is deleterious and must be avoided. The word unduly is used because certain impediments, or �constraints�, are essential to an orderly evacuation. In the absence of constraints, utter chaos is generated, and, as was indicated in a recent survivable crash landing of a transport-type aircraft, tragedy may result. The evidence indicates that the loss of 77 lives in the conflagration which followed the survivable crash landing, resulted from the inability of the occupants to open the main door, possibly greatly aggravated by the pell-mell collection of the occupants against the door. |

| Title: | Flame Sprayed Metallic and Ceramic Coatings For Army Applications | ||||
|---|---|---|---|---|---|
| Author: | Milton Levy, Albert Levitt | ||||
| Abstract: | The drive toward ever higher operating temperatures in Army weapon systems continues unabated since the thermal efficiency and effectiveness of such systems are proportional to their operating temperatures. In the case of missiles and rockets, advances in propellant technology and in system design have outstripped materials development, so that at the present time and in the foreseeable future, lack of suitable materials to resist the extremely high temperatures encountered in such systems is the primary barrier to their continued development. Two major problem areas are involved - internally in the propulsion system and externally on the nose cone and leading edges of aerodynamic control surfaces. Specific components include combustion chamber liners, nozzles, nose' cones, vanes, etc. | ||||

| Title: | A Study of the Flammability of Magnesium | ||||
|---|---|---|---|---|---|
| Author: | Paul Boris | ||||
| Abstract: | This study was performed to provide information on the flammability of magnesium alloys. An investigation of the ignition and burning characteristics was conducted on prepared specimens of four common magnesium alloys. Standard flat specimens were of the same dimensions except for thickness. In addition, typical reciprocating engine castings were tested to determine ignition and burning characteristics under fire conditions closely representing the intensity of an aircraft power plant fire. Each casting varied in thickness from 1/4 inch to 1 inch maximum and was devoid of all internal parts and circulating fluids. The major results of the prepared specimen test are presented as a family of curves which indicate that time to ignition did not vary significantly among the alloys tested, but varied directly with thickness of specimen and airflow over the specimen. After ignition, the airflow accelerated the alloy's burning rate. Tests on the castings revealed a minimum time to ignition of 2 minutes for the smallest (23 pounds) and 4 minutes for the largest (91 pounds). In general, tests indicated that it would be good practice to eliminate sharp edges and protrusions from magnesium alloy casting where possible since these were observed to be more susceptible to ignition. Small magnesium components that are not an integral part of the engine could represent a substantial fire hazard in that they will ignite in a short period of time under intense fire conditions. Previous experience has shown that magnesium fires cannot be extinguished by extinguishing agents presently in use in aircraft power plants and therefore could become a source of reignition of flammables. |
