What is the best thrust-to-weight ratio?

Jet and rocket engines

Jet or rocket engine	Mass	Thrust-to- weight ratio
(kg)
F-1 (Saturn V first stage)	8,391	94.1
NK-33 rocket engine	1,222	136.7
Merlin 1D rocket engine, full-thrust version	467	180.1

How much thrust do Merlin engines produce?

The engine delivers a vacuum thrust of 411 kN (92,500 lbf) and a vacuum specific impulse of 342 s (3.35 km/s).

What is the thrust-to-weight ratio of the Falcon 9?

SpaceX says the Merlin 1D engine has the highest thrust-to-weight ratio — 155-to-1 — of any operational booster engine. The Falcon 9 rocket’s nine main engines together burn about 540 gallons of propellant per second, enough to drain a typical home swimming pool in less than a minute.

What is a measure of the amount of thrust produced in relation to the weight of propellant required?

specific impulse
The rocket weight will define the required value of thrust. Dividing the thrust required by the specific impulse will tell us how much weight flow of propellants our engine must produce. This information determines the physical size of the engine.

Is higher thrust to weight ratio better?

For most flight conditions, an aircraft with a high thrust to weight ratio will also have a high value of excess thrust. High excess thrust results in a high rate of climb. If the thrust to weight ratio is greater than one and the drag is small, the aircraft can accelerate straight up like a rocket.

What fighter aircraft has the best thrust to weight ratio?

The F-15 has always enjoyed a high thrust to weight ratio—it was the first fighter jet that could fly straight up. The F-15QA can hit a maximum takeoff weight of 81,000 pounds, including weapons and fuel, and with all that weight would be considerably more sluggish in the skies.

How much weight can a rocket carry?

The new rocket will be able to carry about 117,000 pounds (53,000 kilograms) of cargo to orbit – about twice the payload-carrying capability of the space shuttle. The Falcon Heavy would launch more than twice as much weight as the Delta 4 heavy, currently the most powerful rocket in operation.

What is the thrust of the Falcon 9 rocket?

1.7 million pounds
Falcon 9 generates more than 1.7 million pounds of thrust at sea level. The nine Merlin engines on the first stage are gradually throttled near the end of first-stage flight to limit launch vehicle acceleration as the rocket’s mass decreases with the burning of fuel.

What plane has the highest thrust-to-weight ratio?

With an 8-to-1 thrust-to-weight ratio—the highest of any jet engine in production at the time—Northrop publicly hailed the J85 for making both aircraft possible. The engine was designed to produce 2,950 pounds of non-afterburning thrust.

When did SpaceX develop the Merlin 1D engine?

The Merlin 1D engine was developed by SpaceX in 2011–2012, with first flight in 2013. The Merlin 1D was originally (April 2011) designed for a sea level thrust of 620 kN (140,000 lbf).

How much thrust will the Falcon Heavy’s Merlin 1D engines produce?

Each of the Falcon Heavy’s 27 Merlin 1D engines would produce 63.5 tonnes thrust at sea level, nearly 1.5 times more than the Merlin 1C engines that powered the first two Falcon 9 rockets.

What is the vacuum thrust to weight ratio of the Merlin engine?

During the August 2011 Joint Propulsion Conference, SpaceX VP of Propulsion Tom Mueller said that the Merlin 1D test engine had demonstrated a vacuum thrust to weight ratio greater than 150:1 and a vacuum specific impulse greater than 309 seconds.   He also said that the engine had performed a 185 second long burn at up to 66.68 tonnes thrust.

How much thrust can meritmerlin 1D throttle at?

Merlin 1D was originally designed to throttle between 100\% and 70\% of maximal thrust, however further refinements since 2013 now allow the engine to throttle to 40\%.
