THRUST EFFICIENCY [5 records]

Record 1 2024-01-17

English

Subject field(s)
  • Aircraft Propulsion Systems
  • Spacecraft
  • Launchers (Astronautics)
DEF

... the propulsive power delivered to the aircraft ... divided by the shaft power input to the propulsor.

OBS

... the propulsive power delivered to the aircraft ... is equal to thrust times airspeed ...

CONT

The more air mass is involved in thrust creation, the higher the propulsive efficiency will be.

Record 4 2001-02-15

English

Subject field(s)
  • Aircraft Propulsion Systems
DEF

Engine thrust divided by aircraft weight.

CONT

The thrust to weight ratio is an efficiency factor for total aircraft propulsion. An aircraft with a high thrust to weight ratio has high acceleration. It has a high value of excess thrust which results in a high rate of climb.

French

Domaine(s)
  • Propulsion des aéronefs
CONT

Le M88-2 est entièrement conçu, développé et fabriqué par Snecma. Par sa conception modulaire, son rapport masse/poussée, ses capacités d'accélération et sa pilotabilité exceptionnelles, il se place au meilleur niveau technologique mondial.

Record 5 1987-01-24

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

A new generation of fuel efficient jet engines is now a reality.... the [CF6-]80C2... met its fuel efficiency target of a 13. 6% improvement over flight test performance of the General Electric CF6-50C. It exceeds its thrust target of 59, 000 pounds, hitting 62, 600 pounds on the very first test.

French

Domaine(s)
  • Propulsion des aéronefs
CONT

Une nouvelle génération de turboréacteurs à faible consommation de carburant est devenue une réalité. [...] le [CF6-]80C2 a tenu ses promesses [...] Le moteur a satisfait à l'objectif de consommation de carburant réduite, à savoir 13,6% de moins, au cours des essais en vol, que le General Electric CF6-50C.
