SR-71 “Blackbird”

Characteristics SR-71:

 *Military airplane
 *To 2 persons (pilot and copilot)
 *It is a spy airplane
 *Is very fast
 *2 enginers


The circuit chosen in this airplane was a circuit of navigation lights

The navigation lights are lights that help to the pilots to know the position the another airplane and know if the airplane is front or no.

Characteristics of navigation lights:

 *The light red is in the wing left
*The light green is in the wing right
*The light white is in the tail of the airplane

Introduction SR-71

Introduction

In this proyect the team will build the electric circuit for the navigation lights of a "Blackbird" military airplane.  The students will develop this project based on learning in class, applying the knowledge of different signatures as: aircraft electricity, aircraft electronics and aircraft structure. The project will have several phases for your elaboration as are:

1.-Design of the electrical circuit on paper.

2.-Elaboration of the electrical circuit in a protoboard.

3.-Creation of the  airplane"Blackbird" to scale.

4.-Construction of the electric circuit in the airplane.

Following these steps we will have as final result the representation of an SR-71 "Blackbird" military airplane in scale with their respective navigational lights to understand the importance and operation of this; as well as to test the ability of the team to apply an electric circuit in an aircraft.

Lockheed Martin F-22 Raptor

It is airplane prestigious because:

• has reach velocity 2120 km/h
• have engine turbofan with postcombustion Pratt & Whitney F119-PW-100
• use technology furtiva
• take off semi vertical
• ability propulsion vertical and horizontal 

This is airplane was made in US  and can  exceed velocity  of March 1,7 (1956 km/h). The use technology  furtiva that use F-22  don't  detect radar correctly  to the fabric . Have the  armament 10 missil and eigth  bomb median.

Parts of f-22 is:

1. wing 
2. wine cellar of arm
3. embroider of arm

                                                                                                                                                      

thermistor temperature sensing alarm

 This kind of temperature alarm will generate a signal when the temperature of the place to be controlled exceeds a predetermined level.

Possible applications:

* A cooling system which doesn't want the temperature to rise and that system don't fulfill the function of keeping the temperature low.

It can posible conect almost everything to the circuit, it can be utilise for inform about an emergency situation, this system can deactivate for a period of time the

 heat source.

* The circuit operates with 12 volts, but can work with any other voltage without affecting its utility.
