Abstract:
An automatic emergency radar and proximity sensor activated protection system that could assist to prevent commercial, private, or military aircraft jet engines from being damaged or destroyed by the installment of a Shielding Blade Assembly which will immediately close when detection of objects such as; birds, debris, or other destructive elements try to enter through the engine intake while the aircraft is in FLIGHT causing the Internal Air Injection Unit (A.I.U.) to supply high volumes of air in order for the engine to stay operational and prevent it from stalling while in FLIGHT.

Description:
BACKGROUND OF THE INVENTION 
     For as long as the jet engine has existed, it has always been plagued by the uncertainty that at any given moment while in flight, the engine or engines of an aircraft could be compromised by external forces. This could normally occur at takeoff when aircraft are most vulnerable to things such as bird strikes or loose debris picked up off the runway. Severe weather fronts containing heavy snow and ice, large hail, or wind shear can be destructive to any jet engine. 
     Currently, most of the more sophisticated jet engines have ice breakers located on the front intake of the main engine section. Deicing and heating systems are also part of similar designs. Unfortunately those preventive systems can only do a fraction of the job and may not be enough when something more overwhelming is about to compromise a jet engine during flight. 
     If an jet engine was to be equipped with a fully automated system that could detect incoming objects, be able to close and shield the intake of the engine, and alternatively supply air to the jet engine(s), then that is where the Thrust Enabling Objective System (T.E.O.S.) would come into play and could conceivably change the level of jet engine vulnerability making air travel safer for all. 
     BRIEF SUMMARY OF THE INVENTION 
     The importance of such an invention is to ensure the safety of a jet aircraft (commercial, private, or military) as well as those who are onboard while in flight by providing a system which automatically blocks out any object which would be destructive to the jet engine(s). 
     System could be activated automatically using an array of sophisticated sensors capable of detecting oncoming threats from long distances. Have the necessary safeguards to making certain that the only element going into the intake of the jet engine is air. To offer the same protective system to older existing jet engines still in operation while incorporate the same system when developing new jet engine designs.

     DETAILED DESCRIPTION OF THE INVENTION 
     Proximity Sensor Array with Electronics: 
     TEOS-002ProximitySensorArrayElectronics.pdf 
       FIG. 6  Sheet 02/12: 
     Process of detecting any solid mass while in flight begins with the proximity sensor array  1 , mounted annually around front air inlet, extended nacelle assembly  10 . 
       FIG. 7  Sheet 03/12: 
     Proximity sensor array  1 , electrically coupled to proximity sensor array cockpit control panel  74 . Panel will house a frequency transducer to transmit continuous signal waves that when bounced off an object will reflect echoes back to proximity sensor array  1 , where they are collected and translated by proximity sensor array cockpit control panel  74 , into a real-time map showing both distance and time to possible impact. Both an audible  70 , and visual  72 , enunciators will alert cockpit crew. 
     When objects are within a strike distance, the microcomputer logic controller  78 , will prepare jet engine for an impact. As part of the failsafe design, each jet engine on an aircraft will have its&#39; own SBA (shielding blade assembly) motor drive circuit  76 , so each engine can be activated only if the threat to that engine is real. 
     At the moment the shielding blade assembly  20 , is activated, feedback from this unit will be transmitted back to the microcomputer logic controller  78 , and the AIU (air injection unit) motor drive circuit  80 , will power up and begin spinning the air injection unit  50 , bringing outside air to supply jet engine and keep it from stalling during flight. 
     Cockpit crew attempting to override system will be locked out by a test/override/operating cockpit function controls  82 . No shutdown permitted whether intentional or accidental. When system has been activated it will continue to function automatically until by which time the system detects no further threats and deactivates the override prevent functions when it is safe again.
