Helicopter Accident Survivability

Helicopter combat survivability

Of all modern aircraft, helicopters are the least survivable due to their low altitude and relatively low speed flight profiles compared with jet aircraft, and their high acoustic and radar signatures. These are inherent limitations of rotary wing aircraft, which cannot be easily or affordably designed out. Formal survivability analysis is centred on two components: the first being susceptibili...

Analysing Evasive Manoeuvre Effectiveness in Helicopter Survivability Simulation

The survivability of survivability

A process algebraic formulation using a weakened form of non-interference in which acceptable performance in the face of certain envelopes of attack/failures can be defined is proposed in [7]. This is presented in the process algebra CSP. Given the unbounded, dynamic nature of many of the systems of interest it may be necessary to use a dynamic calculus such as the pi-calculus or ambient-calculus.

Helicopter emergency medical services accident rates in different international air rescue systems

AIM Each year approximately two to four helicopter emergency medical services (HEMS) crashes occur in Germany. The aim of the present study was to compare crash rates and fatal crash rates in Germany to rates in other countries. MATERIALS AND METHODS A MEDLINE search from 1970 to 2009 was performed using combinations of the keywords "HEMS", "rescue helicopter", "accident", "accident rate", "c...

A correlative investigation of simulated occupant motion and accident report in a helicopter crash.

BACKGROUND In the late 1980's, an Army Apache helicopter crashed during a training mission, resulting in fatal injuries to the rear seat pilot and survivable injuries to the front seat copilot. U.S. Army investigators assessed the aircraft damage and aircrew injuries, and examined the helmets, restraint systems, and crashworthy seats. HYPOTHESIS Computer simulations that approximate an actual...
