I claim: 1. A foreign object deflector for an aircraft engine, the deflector comprising: a base having an inner surface and an outer surface, the base being generally hollow; a screen, the screen being attached to the base by a means for fastening; a connector, the connector having a generally configuration, the connector having a first end and a second end, the first end attached to the base, and the connector second end sized to slidably fit in the engine; a spring, the spring having a main body, a first end and a second end, the spring second end being attached to the base inside surface, the spring main body extending past the base, the spring second end being positioned proximate the screen; and a shock absorbing means, the shock absorbing means attached to the base and connecting the base with the engine, whereby when a foreign object contacts the deflector with a force sufficient to move the spring and the shock absorbing means, the screen, the spring and the shock absorbing means are urged towards the engine, the movement of the screen and the spring being controlled by the shock absorbing means, and the foreign object is prevented from entering the engine. 2. The deflector as described in claim 1, wherein the connector further comprises a means for limiting movement of the deflector. 3. The deflector as described in claim 2, wherein the means for limiting movement comprises one or more O-rings. 4. The deflector as described in claim 1, wherein the shock absorbing means is attached to the base outer surface and attached to the engine outer surface. 5. The deflector as described in claim 4, further comprising an attachment bar, the attachment bar attaching the shock absorbing means to the base and to the engine. 6. The deflector as described in claim 4, wherein the shock absorbing means is a shock absorber. 7. The deflector as described in claim 6, wherein the shock absorbing means further comprises a helper spring, the helper spring being positioned around the shock absorber. 8. The deflector as described in claim 2, wherein the spring is coated with an anticorrosion and antifriction coating. 9. The deflector as described in claim 1, wherein the screen is manufactured from one or more materials selected from the group consisting of rubber, stainless steel, aluminum, carbon fiber and titanium. 10. The deflector as described in claim 4, further comprising a stabilizer bar, the stabilizer bar being attached to the base and connecting the base with the engine. 11. The deflector as described in claim 10, wherein the stabilizer bar is slidably mounted and is generally parallel to the shock absorbing means. 12. The deflector as described in claim 2, wherein the aircraft is chosen from the group consisting of fixed wing aircraft, vertical take-off and landing aircraft and rotary wing aircraft. 13. The deflector as described in claim 4, further comprising a fairing, the fairing covering the shock absorbing means, and the fairing being attached to the base and the engine. 14. A foreign object deflector for an aircraft engine, the deflector comprising: a base having an inner surface and an outer surface, the base being generally hollow; a screen, the screen being attached to the base by a means for fastening; a connector, the connector having a generally configuration, the connector having a first end and a second end, the first end attached to the base, and a means for limiting movement, the first end being attached to the base, and the connector second end sized to slidably fit in the engine; a spring, the spring having a main body, a first end and a second end, the spring second end being attached to the base inside surface, the spring main body extending past the base, the spring second end being positioned proximate the screen; and a shock absorbing means, the shock absorbing means attached to the base and connecting the base with the engine, a stabilizer bar, the stabilizer bar being attached to the base and connecting the base with the engine, the stabilizer bar being slidably mounted and generally parallel to the shock absorbing means, whereby when a foreign object contacts the deflector with a force sufficient to move the spring and the shock absorbing means, the screen, the spring and the shock absorbing means are urged towards the engine, the movement of the screen and the spring being controlled by the shock absorbing means, and the foreign object is prevented from entering the engine. 15. The deflector as described in claim 14, wherein the spring is coated with an anticorrosion and antifriction coating. 16. The deflector as described in claim 14, wherein the screen is manufactured from one or more materials selected from the group consisting of rubber, stainless steel, aluminum, carbon fiber and titanium. 17. A foreign object deflector for an aircraft engine, the deflector comprising: a base having an inner surface and an outer surface, and an attachment bar extending from the outer surface, the base being generally hollow; a screen, the screen being attached to the base by a plurality of fasteners; a connector, the connector having a generally configuration, the connector having a first end and a second end, and a means for limiting movement, the first end being attached to the base, and the connector second end sized to slidably fit in the engine; a spring, the spring having a main body, a first end and a second end, the spring second end being attached to the base inside surface by a means for attaching, the spring main body extending past the base, the spring second end being positioned proximate the screen; and a shock absorbing means, the shock absorbing means attached to the base outer surface by the attachment bar and attached to the engine outer surface by a second attachment bar; whereby when a foreign object contacts the deflector with a force sufficient to move the spring and the shock absorbing means, the screen, the spring and the shock absorbing means are urged towards the engine, the movement of the screen and the spring being controlled by the shock absorbing means, and the foreign object is prevented from entering the engine. 18. The deflector as described in claim 17, wherein the spring is coated with an anticorrosion and antifriction coating. 19. The deflector as described in claim 17, wherein the screen is manufactured from one or more materials selected from the group consisting of rubber, stainless steel, aluminum, carbon fiber and titanium. 20.
