The power required to keep a Boeing 737-300 flying at a constant altitude and speed is 7.2 × 106 watts. The rate of fuel burn necessary for the engines to produce enough power to keep the airplane flying can be calculated from the total power requirement.

## How much horsepower did Titanic have?

RMS Titanic

Two reciprocating steam engines – with a combined output of 30,000 horsepower and each weighing 720 tonnes – and one low-pressure turbine powered the Titanic. They needed the steam produced by 29 boilers, each capable of holding more than 48 tonnes of water.

## Why is jet fuel so cheap?

Jet A fuel consistently costs less than 100LL due to its simpler refining process, ease of transportation (via pipelines because it does not contain lead), and economies of scale from the volume of demand.

## How powerful is a 777 engine?

The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 lbf (360 to 510 kN).

## How much horsepower does a 777 engine have?

Posted by McNally on March 3, 2022. In 1 megawatt measurements, 1401 horsepower is generated. As part of cruising a Boeing 777 with two GE 90-115B engines, each engine is required to generate about 23 Megawatts of power per hour while the aircraft is full. There are 30 people here.

## How much horsepower does a helicopter have?

How Much Horsepower Does A Helicopter Engine Have? turboshafts are common on large helicopters. It consists of two Lotarev D-136 vehicles at 11,400 HP each, in comparison with the Sikorsky CH-53E Super Stallion which only consumes three General Electric T64 models at 4,380 HP each.

## What’s the most powerful engine in the world?

Developed by Wärtsilä Corporation, the 14-cylinder Wärtsilä RT-flex96C engine is also the world’s most powerful engine with an output of 80,080 kW (108,920 bhp). The 14-cylinder Wärtsilä RT-flex96C engine is a major breakthrough for ship propulsion.

## How much horsepower is in a human?

When considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours.

## Can a 747 take off with 2 engines?

Question: If two engines on the same wing of a 747-400 fail, can the jet fly on the other two? Answer: It depends on the weight and the altitude. At very heavy weights and high altitude, maintaining altitude on two engines may not be possible. At lighter weights, it may be possible to maintain altitude with 2 engines.

## Why does a 747 have 5 engines?

The extra engine adds drag to one side of the plane. Consequently, pilots have to adjust the power on the other side to compensate. The special cargo meant that the aircraft was heavier and required additional stops.

## How many kW is a jet engine?

How Many Kw Is A Jet Engine? Smaller planes used a gas-cooled four- or six- cylinder airplane that required a power output of up to 400 horsepower (300 kW) per engine. Engineless planes such as military aircraft require turbine engines that power up to 300 kW (375 kWh).

## Why are jet engines so powerful?

A jet engine is meticulously designed to hoover up huge amounts of air and burn it with vast amounts of fuel (roughly in the ratio 50 parts air to one part fuel), so the main reason why it makes more power is because it can burn more fuel.

## How much power does it take to fly a plane?

However, takeoff and landing require much more power. Regardless of how far an e-VTOL travels, our analysis predicts takeoff and landing combined will require between 8,000 and 10,000 watt-hours per trip. This is about half the energy available in most compact electric cars, like a Nissan Leaf.
