Hi! Campini CS3 side view large image.
I see two nose devices. One device is compressor. What is nose cone?

"A characteristic feature of CS3 was the presence of a compressor powered by a central engine and who started his work at heights exceeding 4000 m. Compressor maintained constant pressure for the three main engines at altitudes between 5000 and 17000 meters; He also guaranteed the pressurization and sealing support cabin control.
Three-speed compressor was equipped with three rotors, two of which were taken outside air, sending a third rotor, who accompanied him to the inputs of the individual compressor motors.
With increasing height provided a significant increase in power, so at an altitude of 17000 m lateral engines developed would power about 1000 HP, passing it on the screws, while the Central engine would transmit 800 HP compressor, zarezerviruâ 200 HP screw balance.
Select only the compressor had the advantage of being allowed to use the normal engines that are in production, without requiring the preparation of a special engine with supercharged engines at high altitudes. In addition there were other advantages, including better performance than offered by large size compressors.
The use of radial engines to increase power instead of Isotta Fraschini Asso l. 121 would further increase the horizontal speed and climb rate.
Under the designation "rocket was proposed CS4 version with the three main engines, which included the same type Kampini, tested previously on the single-engine plane. In this version of speed increased because in addition to the power of the engine was also used power obtained from direct combustion of petrol in combustion chamber.
The official reaction to CS3/CS4 project was very cautious. DGCA, after carefully studying the report submitted by the engineer Kampini, expressed serious doubts about the veracity of the data project. Power absorbed by the compressor, its predecessor into account only to the extent necessary to supply three engines (i.e. without taking into account the need for cabin pressurization), when the alleged efficiency compressor was 0.6 810 HP vs 750 HP, proposed by engineer. The magnitude of compression does not exceed 3.5 values against 6, necessary to obtain the desired pressure, while the throughput of the compressor was fairly low, averaging 0.5 m ³/sec instead of almost 2.5 m ³/s needed to recharge three motors.
Considerable difficulties presented would be cooling engines due to the extreme rarity of air in the stratosphere. In addition, the screws of the side engines would not have been able to develop the same torque at 17000 m (where the air density is reduced to 1/5 of normal) at 5000 m as a result of the efficiency of the compressors to meet up to 13000-meter height, sharply decreased at high altitudes.
Total motor Group excluding damn jet propulsion was considerable constructive given the difficulties and required a high ratio of the compressor, and as a result, oversize dimensions of the compressor, which was not expected from the calculations of the designer. It was also noted that in calculating the amount of air is not directed into the cabin, in addition to high speed were not are average losses of leakage and losses due to enemy resistance (hit).
As far as reactive versions, it was emphasized the strong reduction in connection with the work range of the jets, whose thermal impact was very low.
Placing military load was considered extremely irrational and excessive in relation to constructive capabilities: payload for aircraft with similar characteristics was calculated at approximately 35% of the total weight, and thus the value of load 4000 kg seemed reassuringly proposed 7500 kg. Consequently, payload dramatically declined from 5000 to 1000 kg."

Where is the radiator? Circular radiator located inside of the engine nacelle?
