Has the fewest illustrations of any Railway Series story, with four. In early editions of this book, the boys were described as being "as black as niggers " after Henry sneezed at them.

SAGE 1 — Open Rotor Open rotor technologies offer the potential for significant reductions in fuel burn and CO2 emissions relative to turbofan engines of equivalent thrust.

Higher propulsive efficiencies are achieved for turbofans by increasing the bypass ratio through increases in fan diameter but there is a diminishing return to this improvement as nacelle diameters and consequently weight and drag increase.

Open rotor engines remove this limitation by operating the propeller blades without a surrounding nacelle, thus enabling ultrahigh bypass ratios to be achieved.

Further improvements in propulsive efficiency can be gained for open rotor engines by using a second row of propeller blades rotating in opposition to the front row to remove the spin from the column of air, thereby producing a more direct thrust.

The technical challenges of counter rotating open rotor engines are many, but are principally: Reduction of the noise created by the propeller blades to counter the loss of attenuation provided by a turbofan nacelle. Definition of the propeller system to reduce the noise created by the counter rotating blades counter rotating slotted discs in close proximity is the basis siren design and blade interaction noise was the principal issue noted when the open rotor engines were demonstrated in the s.

Complexity of communications and blade pitch control through the counter rotating power transmissions system. Installation of the open rotor engine on the airframe: In conventional engine-to-wing configurations with turbofans, the engines are isolated from the airframe by the nacelle.

However, with open rotors, the airflow through the propellers interacts with the supporting airframe structure in a different manner, hence the installation impacts on the engine system noise and efficiency.

This work was completed in and has focused on validating extreme blade angles of attack against rig Z08 blade surface measurements. Component integrity and evaluation of blade design and material options, including a sample test programme under high strain rate, during shear extension experiments.

This project was completed in Validation of methods for stability, flutter and forced response against available rig data. This programme was completed in Validation of far-field and near-field noise methods for open rotor designs using available rig data.

All the engines now have numbers as well as names; you will see them in the pictures. They are as follows: Thomas 1, Edward 2, Henry 3, Gordon 4, James 5, Percy 6. The Green Engine Research Network intend to support the development of research activities and new technologies in the following fields: Fluid-dynamics applied to combustion phenomena, aerospace propulsion, flow active control, industrial design (Combustion and Propulsion Lab).The Combustion and Propulsion Lab is a part of the .

For large short- and medium-range aircraft, the first GTF engines will be the most advanced and fuel-efficient state-of-the art solution entering service shortly. To realise this potential, Clean Sky 2 has to deliver convincing proof that the CROR engine concept can be manufactured, installed and operated in an industrial environment comparable to other latest state-of-the-art concepts.

The SAGE 2 project focuses on demonstrating the following technologies: The delivery of the SAGE 2 demonstrator to the ground test facility is planned by mid and the ground test will start in Q3 of The current assumption is to use the Airbus A MSN test aircraft as a flight test vehicle, with one full size CROR pusher engine attached to a representative pylon and engine mount installed at the port board side of the rear fuselage.
