[edit] Request for info

Hello! My name is Sergey Bondarenko. I am very interesting in air safety control especially flight data recorders! Actually I cannot find discription of any one! I am especially interesting in harware, main principal of operation. It would be very kind of you if you help me with it. Beforehand thankful. Oh by the way my e- mail is bondarenkoss@ukr.net, if you have some information, please receive it there!

[edit] History of FDR

I think one of the first (maybe the first) FDR was an Finnish "Mata Hara" invented during early 40's.

Mata Hara . Martti Kujansuu

I'm interested to know about failure rates in FDR and CVRs (i.e. from excessive damage); I'm also interested in finding out how regularly the FDRs and CVRs are not found.

[edit] Developer of the "black box" from University of Minnesota

James Ryan was born on November 27, 1903 in LeClaire, Iowa. In 1925 he received his B.S. in mechanical engineering from the University of Iowa, and in 1929, he received his M.S. in mechanical engineering from the University of Pittsburgh, doing his graduate work at Stanford University. Ryan came to the University of Minnesota as an assistant professor in mechanical engineering in 1931, being promoted to associate professor in 1940, and becoming a full professor in 1950.

Concerned about automobile safety, in 1949 Ryan began crashing cars into walls while his students observed, to complete his own testing in auto safety experiments. As a result, he invented the retractable seat belt, which he patented in 1963. Although nicknamed "Crash" Ryan, he was never injured in the experiments, and federal government researchers frequently consulted him on research. He also invented the flight data recorder, or "black box" patented in 1963, and now required on all commercial airlines. He conducted experiments under grants from the Office of Naval research, the Naval Medical Research Institute, the National Research Council, the United States Air Force, and the United States Public Health Service.

In 1963, Ryan retired because of a rheumatic heart condition. He passed away on May 31, 1973 at the age of 69. —The preceding unsigned comment was added by 128.101.7.29 (talk) 19:38, 9 March 2007 (UTC).

As the article clearly states, Ryan did NOT "invent" the flight data recorder. The David Warren ARL one predated his by several years. Garth M 02:09, 29 May 2007 (UTC)

[edit] Hawker Siddeley Trident First?

I put a citation request on the Hawker being the first comment. I am updating the 1960 New York air disaster article and have a New York Times reference about the DC-8 in that crash having a flight recorder that was the first to be used. The hawker article says it made its maiden voyage in 1962. Americasroof 22:32, 13 August 2007 (UTC)

[edit] Finnish inventor

Actually, the inventor of the black box is Veijo Hietala. In 1940 in Härmälä. "Sillä itse asiassa musta laatikkko on suomalainen keksintö, jonka kehityskaaren jäljet johtavat Tampereelle, valtion lentokonetehtaalle. Siellä dipl. ins. Veijo Hietala lähti vuonna 1942 kehittämään laitetta, joka pystyisi lennon aikana taltioimaan useita lentokoneeseen vaikuttavia voimia ja lentäjän tekemiä toimenpiteitä.

Tampereella kehitelty laite oli koelentopiirturi, jota ryhdyttiin kutsumaan "Mata Hariksi" ensimmäisen maailmansodan kuuluisan naisvakoojan mukaisesti. Lentokoneisiin mustat laatikot alkoivat ilmestyä 1950-luvulla.

Sittemmin laite on tietysti paljon kehittynyt. Useimmissa lentokonetyypeissä musta laatikko sisältää lentopiirturin ja äänityslaitteen. Piirturi rekisteröi kellonajan, koneen lentonopeuden, lentokorkeuden ja kurssin. Suurimmissa konetyypeissä taltioidaan myös laskutelineiden ja peräsimen asento sekä moottoreiden toiminta onnettomuutta edeltäneiden 25 tunnin ajalta. Myös ohjaamon äänet rekisteröityvät. Varsinaiset laitteet (Flight Recorder ja Cockpit Voice Recorder) ovat nykyään oranssin värisiä löytämisen helpottamiseksi. Niitä kutsutaan yhä mustiksi laatikoiksi, sillä aikaisemmin ne olivatkin väriltään mustia.

Mustat laatikot kestävät yli tuhannen asteen kuumuutta. Pudotessaan mereen laatikko alkaa lähettää ultraäänisignaalia, jonka avulla se voidaan paikantaa 30 päivän ajan jopa kuuden kilometrin syvyydestä. " The quotation is from Turun Sanomat. It says that the Mata Hari name is from the first World War from one female spy. —Preceding unsigned comment added by 84.248.120.105 (talk) 17:50, 3 December 2007 (UTC)

[edit] Adolf Hitler invented Black Box?

I heard somewhere that Hitler told Marshal Erhard Milch that all planes should have voice recorders installed? Is it true? —Preceding unsigned comment added by Cesarz (talk • contribs) 00:46, 28 January 2008 (UTC)
