Design and development
The United States Air Corps wanted the aircraft to perform high altitude research and to test the feasibility of a pressurized cabin.
The Corps contracted with Lockheed Aircraft Corporation to produce the aircraft at a total cost of $112,197.
The requirements called for an aircraft capable of flying at no less than 25,000 ft (7,620 m) and having an endurance of 10 hours with at least 2 hours above 25,000 ft (7,620 m).

[Vous devez être inscrit et connecté pour voir ce lien] Carl Greene and John Younger, both structures experts who worked for the Air Corps Engineering Division at [Vous devez être inscrit et connecté pour voir ce lien] in Ohio were responsible for the design of the pressurized cabin structure.
Greene and Younger worked with Lockheed to modify a Model 10 Electra with a new fuselage consisting a circular cross section that was able to withstand up to a 10 psi differential.
New, smaller windows were used to prevent a possible blowout while operating at high pressure differentials.
The cabin pressurization was provided by bleeding air from the engines' [Vous devez être inscrit et connecté pour voir ce lien], the compressor outlet fed into the cabin and was controlled by the flight engineer.

This system was able to maintain a cabin altitude of 12,000 ft (3,658 m) while flying at 30,000 ft (9,144 m).[Vous devez être inscrit et connecté pour voir ce lien]
The fuselage was divided into two compartments, a forward pressurized compartment, and an aft unpressurized compartment.
The forward compartment housed two pilots, a flight engineer, and up to two passengers.
The aft compartment provided accommodations for one passenger and could only be used at low altitudes since it lacked
pressurization.[Vous devez être inscrit et connecté pour voir ce lien]

The XC-35 was fitted with two [Vous devez être inscrit et connecté pour voir ce lien] engines of 550 [Vous devez être inscrit et connecté pour voir ce lien] (410 kW) each compared to the two Pratt & Whitney [Vous devez être inscrit et connecté pour voir ce lien] of 450 hp (336 kW) fitted to the base Model 10 Electra.
The engines featured a turbo supercharger to permit the engines to operate in the thin air at high altitudes.
