An aerial load lifting system features a non-rigid or blimp-type dirigible providing a lighter-than-air envelope that is placed within a structural shell. The system is designed so that the envelope provides essentially neutral buoyancy for the structure, leaving only the cargo weight to be lifted by the rotors. The structural shell supports the engine, fuel tank, rotors, and transmission system that power the lift and vectoring of the aircraft, in addition to supporting the cargo load. The structural shell transfers the weight of the load directly to the location of the rotors, thus avoiding stress on the envelope.

1. An aerial load lifting system for transporting a load, comprising: an envelope filled with a lighter-than-air gaseous substance;a structural shell for supporting the load, wherein the structural shell is shaped to allow the envelope to be slid horizontally into the structural shell such that the structural shell is surrounded at least in part by the structural shell; anda power train system including at least one engine supported by the structural shell and located above the envelope, and at least one rotor oriented in a substantially horizontal plane supported by the structural shell and located above the envelope, wherein the envelope provides a buoyant force essentially to offset the weight of the structural shell and the power train system, wherein the power train system provides a lifting force capable of lifting the load. 2. The system of claim 1, wherein the structural shell has an opening through which the envelope may be inserted. 3. The system of claim 1, wherein the envelope has a plurality of internal bladders which maintain the lighter-than-air gaseous substance at a constant pressure and at least one internal support positioned underneath the at least one rotor to allow the weight of a cargo to be transferred directly to the at least one rotor. 4. The system of claim 1, wherein the gaseous substance is helium. 5. The system of claim 1, wherein the structural shell is primarily formed of aluminum, titanium, or a composite material. 6. The system of claim 1, wherein the structural shell supports a cockpit for housing a pilot. 7. The system of claim 6, wherein the cockpit is located to provide a pilot with an unobstructed view of the load during a loading or unloading process. 8. The system of claim 1, wherein the system is operated using a radio control system. 9. The system of claim 1, wherein the structural shell includes plurality of fixtures located on a bottom side of the structural shell to which cargo cables may be attached. 10. The system of claim 1, wherein the power train system includes a combining transmission to combine power from multiple engines to one or more drive shafts coupled to the at least one rotor. 11. The system of claim 1, wherein the power train includes two motors coupled to the at least one rotor. 12. The system of claim 1, wherein the structure shell further supports retractable landing gear. 13. An aerial transportation system, comprising: an envelope filled with a lighter-than-air gaseous substance;a structural shell surrounding the envelope at least in part wherein the structural shell is shaped to allow the envelope to be slid horizontally into the structural shell such that the structural shell is surrounded at least in part by the structural shell; anda power train system including at least one engine and at least one rotor, the power train system located above the envelope;wherein the envelope provides a buoyant force essentially to offset the weight of the structural shell and the power train system and wherein the power train system provides a lifting force, and wherein the at least one rotor is located above the envelope and the at least one engine is located above the envelope. 14. The system of claim 13, wherein the envelope has a plurality of internal bladders which maintain the lighter-than-air gaseous substance at a constant pressure. 15. The system of claim 13, wherein the structural shell is primarily formed of aluminum, titanium, or a composite material. 16. The system of claim 13, wherein the structural shell supports a cockpit for housing a pilot. 17. The system of claim 16, wherein the cockpit is located to provide a pilot with an unobstructed view of the load during a loading or unloading process. 18. The system of claim 13, wherein the structure shell further supports retractable landing gear. 19. The system of claim 1, wherein structural shell includes an non-linear structural shell element positioned along approximately ¾ of the envelope, the non-linear structural shell element having at least two ending portions, each having at least one fixture to which cargo cables may be attached, and a linear structural shell element positioned between the at least two ending portions of the non-linear structural shell element, the linear structural shell element positioned to receive a resultant compressive force from the load. 20. The system of claim 1, wherein the envelope is positioned between the at least one rotor and the load. 21. The aerial load lifting system for transporting a load of claim 1, wherein the envelope includes at least one internal support located substantially directly below the at least one rotor and connected between the at least one rotor, wherein the at least one internal support transfers weight force from the load directly to the at least one rotor. 22. The aerial load lifting system for transporting a load of claim 1, wherein the structural shell has a substantially cylindrical shape and further comprises a plurality of cables supporting a removable quantity of cargo, wherein a first portion of the plurality of cables are affixed to a left side of the structural shell in a position underneath the rotor and a second portion of the plurality of cables are affixed to a right side of the structural shell in a position underneath the rotor, opposite the left side of the structural shell.
