This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: LES OBSERVATIONS EXPERIMENTALES MONTRENT QUE LES MOTEURS A ALLUMAGE COMMANDE EN FONCTIONNEMENT TRANSITOIRE SONT SOUMIS A UN DESEQUILIBRE MOMENTANE DE RICHESSE. CE PHENOMENE PEUT ETRE A L'ORIGINE D'EXTINCTION PAUVRE ET/OU DE FORTES EMISSIONS DE POLLUANTS. CETTE THESE DECRIT UN MODELE QUI APPROCHE CE PHENOMENE, PAR LE TRAITEMENT D'UN ECOULEMENT INSTATIONNAIRE ANNULAIRE DISPERSE A DEUX CONSTITUANTS, AIR ET CARBURANT (FILM ET GOUTTELETTES). LES RESULTATS MONTRENT QUE C'EST LE FILM LIQUIDE QUI PRESENTE LE TEMPS DE REPONSE LE PLUS GRAND. PAR AILLEURS ET BIEN QUE CELLE-CI AIT UN TEMPS DE REPONSE FAIBLE, LA POPULATION DE GOUTTELETTES PEUT CONTRIBUER NOTABLEMENT A ENTRETENIR UN DESEQUILIBRE DE RICHESSE

Symposium and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Conference Proceedings contains 38 papers presented at the Propulsion and Energetics Panel 73rd Symposium on 'Aircraft Fire Safety' which was held 22 - 26 May 1989 in Sintra, Portugal. The Symposium was arranged in the following sessions: Review of Fire-Related Aircraft Accidents (3); Fire Safety Standards and Research Programmes (6); Aircraft Internal Fires (9); Aircraft External Fires (2); Fire Safety of Military Weapon Systems (3); Fire Hardening by Advanced Materials and Structural Design (8); Passenger Behaviour in Emergency Situations (3); and Passenger Protective Equipment (4). The Technical Evaluation Report and and Addendum are included at the beginning of the Proceedings. Questions and answers of the discussions follow each paper. The last AGARD review on the subject took place in a Specialists' Meeting in 1975, followed by a Working Group Report in 1979 and Lecture Series in 1982. The purpose of the Symposium was a review of the present state-of-the-art and of the last improvements. Although the safety standards in aviation are already very high, there is still room for improvements. They are listed in the Conclusions and Recommendations of the Technical Evaluation Report and in the Addendum.

Available in PDF, EPUB and Kindle. Book excerpt: The future evolution of the debris environment will be forecast on the basis of traffic models and possible hazard mitigation practices. The text shows how large trackable objects will have re-entry pinpointed and predictions made on related risk assessment for possible ground impact. Models will also be described for meteoroids which are also a prevailing risk.
