Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. . Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver(s), vehicle(s), roadway and gen
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.
Delta-v is typically provided by the thrust of a rocket engine, but can be created by other engines. The time-rate of change of delta-v is the magnitude of the acceleration caused by the engines, i.e., the thrust per total vehicle mass. The actual acceleration vector would be found by adding thrust per mass on to the gravity vector and the ...
The applied change in velocity of each maneuver is referred to as delta-v (). The delta-v for all the expected maneuvers are estimated for a mission are summarized in a delta-v budget. With a good approximation of the delta-v budget designers can estimate the propellant required for planned maneuvers.
[9] [10] [11] The concept has transcended into accident reconstruction and engineering. [ 12 ] This distance is typically both determined and constrained by the proximate edge of clear visibility, but it may be attenuated to a margin of which beyond hazards may reasonably be expected to spontaneously appear.
The first use of forensic animation was in Connors v. United States, both sides used computer re-creations and animations in a case surrounding the crash of Delta Flight 191 on August 2, 1985. [8] The crash resulted in the deaths of 137 people and extensive property damage.
Different criteria are used to figure out how safe a structure is in a crash, depending on the type of impact and the vehicle involved. Crashworthiness may be assessed either prospectively, using computer models (e.g., RADIOSS , LS-DYNA , PAM-CRASH , MSC Dytran , MADYMO ) or experiments, or retrospectively, by analyzing crash outcomes.
The crew consisted of Captain George T. Kunz (age 55), employed by National Airlines since 1956, who had qualified to fly the Boeing 727 in 1967 and accumulated 18,109 flight hours in his career with 5,358 hours on the Boeing 727; First Officer Leonard G. Sanderson Jr. (31), employed by National Airlines since 1976, with 4,848 flight hours of which 842 hours were on the Boeing 727; and Flight ...
