Safety and good packaging in
I - Military Air Transport:
1) The security and protection of military aircraft.
2) L'auto-refroidissement de l'intérieur de l'avion surchauffé
en cas d'une attaque directe par des projectiles.2) Self-cooling of the interior of the overheated aircraft
in the event of a direct attack by projectiles.
3) Le Transport des bombes chargées de gaz et des armes sophis
tiquées et sensibles à la chaleur.3) Transport of gas-loaded bombs and sophis weapons
ticked and sensitive to heat.
II- Le Transport Aérien Civil:
1) La protection des voyageurs contre le terrorisme.II- Civil Air Transport:
1) The protection of travelers against terrorism.
2) L'amélioration de transport des produits alimentaires et autres. 2) Improving the transport of food and other products.
Cette invention est une méthode pour la sécurité dans les moyens de transports aériens, soit pour:
1) Protéger les voyageurs contre des opérations de terroristes.This invention is a method for safety in air transport means, either for:
1) Protect travelers from terrorist operations.
2) Le bon conditionnement du transport des marchandises, produits
alimentaires (frais, secs ou empaquettés, ....)
3) La sécurité du transport du matériel militaire (armes, fuel,
produits chimiques, armes sophistiquées, bombes contenant du
gaz liquide, etc....).2) The correct packaging of the transport of goods, products
food (fresh, dry or packaged, etc.)
3) The security of the transport of military equipment (weapons, fuel,
chemicals, sophisticated weapons, bombs containing
liquid gas, etc.).
DANS LE CAS CIVIL:
L'idée principale de cette méthode dans le cas d'actions
terroristes est basée sur l'utilisation d'un gaz anesthésiant
momentané, afin d'endormir l'ensemble des voyageurs, exceptés
les gardiens ou membres de l'équipage de l'avion qui doivent
être isolés du reste de l'avion avec leurs masques. On saisit
cette période d'incapacité pour maîtriser la situation et neu
traliser les terroristes. Ensuite commence rapidement l'opéra
tion d'évacuation de l'air mélangé avec le gaz anesthésiant,
et son remplacement par de l'air frais et conditionné.IN THE CIVIL CASE:
The main idea of this method in the case of actions
terrorists is based on the use of an anesthetic gas
momentary, in order to put all travelers to sleep, except
custodians or aircrew who are responsible for
be isolated from the rest of the plane with their masks. We grab
this period of incapacity to master the situation and neu
track down terrorists. Then the opera begins quickly
evacuation of the air mixed with the anesthetic gas,
and replacing it with fresh, conditioned air.
Comment exécuter les deux opérations d'anesthésie et d'apport d' |air frais et conditionné. How to perform the two operations of anesthesia and supply of fresh and conditioned air.
a) L'anesthésie: dans le cas où l'avion est attaqué par un ou
plusieurs terroristes, l'ouverture des valves de réservoir
du gaz anesthésiant peut-être effectué par l'un des membres
de l'équipage, par l'un des gardiens, ou par télécommande à
distance (aéroport - autres avions dans le voisinage). La
quantité de gaz doit être dosée en fonction de l'espace vo
yageurs. Le circuit du gaz est le même circuit d'air clima
tisé de l'avion.a) Anesthesia: in the event that the aircraft is attacked by one or
several terrorists, opening tank valves
anesthetic gas can be made by one of the members
of the crew, by one of the guards, or by remote control
distance (airport - other planes in the vicinity). The
quantity of gas must be dosed according to the space vo
swimmers. The gas circuit is the same clima air circuit
fired from the plane.
b) Purification de l'air mélangé avec le gaz anesthésiant:
La pompe (P1) aspire l'air de l'extérieur (entrée (El) fig.l)
avec les valves (V1), (V2), (V4) et (V5) ouvertes, les valves
(V3) et (V6) fermées. L'air passe à travers des filtres (Fl,
F2, F3) (autant de filtres que nécessaire) pour purifier l'air
avant d'être climatisé par la chambre de climatisation (ch)
(fig.l). Dans le même temps la pompe (P2) évacue l'air mélangé
avec le gaz anesthésiant à l'extérieur via la valve (V4)
(sortie (E3) ). b) Purification of the air mixed with the anesthetic gas:
The pump (P1) sucks in air from the outside (inlet (El) fig.l)
with the valves (V1), (V2), (V4) and (V5) open, the valves
(V3) and (V6) closed. Air passes through filters (Fl,
F2, F3) (as many filters as necessary) to purify the air
before being air conditioned by the air conditioning chamber (ch)
(fig.l). At the same time the pump (P2) evacuates the mixed air
with the anesthetic gas outside via the valve (V4)
(output (E3)).
c) Le conditionnement et la climatisation de l'air:
Après le passage à travers les filtres (F2), (F3)
le compresseur (C1) amène l'air filtré dans la chambre de
climatisation (qui contient un ou deux petits appareils de
climatisation pour contrôler la température et le taux d'hu
midité de l'air climatisé) avant d'entrer dans l'espace voya
geurs. Pour améliorer l'efficacité de la chambre de climati
sation, et pour économiser l'énergie électrique utilisée, il
faut que le passage de l'air climatisé dans la chambre sorte
à travers des orifices coniques d'un disque métallique, à une
pression de 1 à 5 atmosphères, et ensuite retombe à une pres
sion de 1 atmosphère, à la sortie du disque.Cette opération
aide à diminuer la température de l'air climatisé. I1 faut donc
prendre en compte cet effet en réglant la température finale
de l'air climatisé entrant dans l'espace voyageurs.c) Air conditioning and air conditioning:
After passing through the filters (F2), (F3)
the compressor (C1) brings the filtered air into the
air conditioning (which contains one or two small appliances
air conditioning to control temperature and oil level
air conditioning) before entering the space
geurs. To improve the efficiency of the climate chamber
sation, and to save the electrical energy used, it
the air conditioning passage in the room must come out
through conical orifices of a metal disc, at a
pressure from 1 to 5 atmospheres, and then drops to a pres
1 atmosphere at the exit of the disc.
helps lower the temperature of the air conditioning. We must therefore
take this effect into account when adjusting the final temperature
air conditioning entering the passenger area.
d) Purifier et climatiser r air interne de l'avion:
On peut purifier l'air interne de l'avion en circuit fermé par
la fermeture des valves (V1), (V2), (V3) et (V4), et l'ouverture
des valves (V5) et (V6). A ce moment-là, la pompe (P2) aspire 1'
air interne de l'avion par l'entrée (E2) et le refoule une deu
xième fois vers les filtres et la chambre de climatisation (ch).d) Purify and air condition the internal air of the aircraft:
The internal air of the airplane can be purified in a closed circuit by
closing the valves (V1), (V2), (V3) and (V4), and opening
valves (V5) and (V6). At this time, the pump (P2) sucks 1 '
internal air of the aircraft through the inlet (E2) and expels two
xth time to the filters and the air conditioning chamber (ch).
L'air sortant sera purifié des fumées de cigarettes, vapeur d'eau,
et C02.The outgoing air will be purified from cigarette smoke, water vapor,
and C02.
e) On utilise deux chambres de climatisation (ch) pour avoir un cou
rant continu d'air climatisé poussé à l'intérieur de l'avion. e) We use two air conditioning chambers (ch) to have a neck
continuous flow of air conditioning pushed inside the aircraft.
DANS LE CAS DES TRANSPORTS DES PRODUITS ALIMENTAIRES ET D'AUTRES
PRODUITS: a) Si le transport des produits alimentaires nécessite une réfrigé
ration, on utilise le circuit de la figure 1 avec les valves (V1)
(V2), (V5) et (V6) ouvertes, les valves (V3) et (V4) fermées, et
avec la mise en marche des pompes (P1) et (P2) ainsi que du com
presseur (Cl). A la sortie de la chambre de climatisation (ch),
on peut avoir la température et le taux d'humidité voulus.IN THE CASE OF TRANSPORT OF FOOD AND OTHER PRODUCTS
PRODUCTS: a) If the transport of food products requires refrigeration
ration, we use the circuit of figure 1 with the valves (V1)
(V2), (V5) and (V6) open, the valves (V3) and (V4) closed, and
with the starting of the pumps (P1) and (P2) as well as the com
presser (Cl). At the exit of the air conditioning chamber (ch),
you can have the desired temperature and humidity.
b) Pour éviter la création d'un climat favorable au développement
des bactéries qui peuvent détériorer les produits transportés
( cas de fruits, légumes, viandes surgelées, poissons surgelés, ...), on utilise le circuit fig.l. les valves (V6) et (V5) sont
ouvertes et les autres fermées. La mise en marche de la pompe (P2)
aide à obtenir la température et la pression qui peuvent prolonger
la période de stockage et/ou du transport. Cette opération empê
che la formation des bactéries et aussi, permet de se débarasser
des insectes.b) To avoid creating a climate favorable to development
bacteria that can spoil the products transported
(case of fruits, vegetables, frozen meats, frozen fish, ...), use the circuit fig.l. the valves (V6) and (V5) are
open and the others closed. Starting the pump (P2)
helps to get the temperature and pressure that can prolong
the period of storage and / or transport. This operation prevents
che the formation of bacteria and also, allows to get rid
insects.
DANS LE CAS MILITAIRE:
Pour la sécurité de l'avion de transport militaire, on contrôle
le conditionnement de l'air interne et sa pression par l'utilisa
tion du circuit figure 1. C'est par la baisse de température de
l'air sortant de la chambre de climatisation et sa pression, que
liron peut empêcher l'explosion ou le déclenchement du feu, sur
tout dans le cas de transports d'armes chimiques, de fuel, de bom
bes de gaz et matériaux sensibles à la chaleur. Nous employons
donc la même technique soit pour renouveler l'air ambiant en cir
cuit fermé, soit pour purifier, climatiser et régler la pression
de l'air du compartiment réservé. C'est par la fermeture des val
ves (V3, (V4) et l'ouverture des autres que l'on peut climatiser
l'air de l'espace réservé au transport et aussi contrôler la pres
sion. IN THE MILITARY CASE:
For the security of the military transport aircraft, we control
the internal air conditioning and its pressure by the user
tion of the circuit figure 1. It is by the drop in temperature of
the air leaving the air conditioning chamber and its pressure, which
liron can prevent the explosion or the outbreak of fire, on
everything in the case of transport of chemical weapons, fuel, bom
bes gas and heat sensitive materials. We employ
so the same technique is to renew the ambient air in cir
cooked closed, either to purify, condition and regulate the pressure
air from the reserved compartment. It is by closing the val
ves (V3, (V4) and the opening of others that can be conditioned
the air in the space reserved for transport and also check the pres
if we.
