Jahrzehnte ago, we were promised jetpacks. Here's where they are right now ...

What happened to all of those jetpacks we received? We can''t be certain who got it, but someone did, and we want them right now!

Whatever the truth, the concept of jetpacks is engrained in our cultural psyche, so certainly it can only be a matter of time before they arrive?

Let''s get to know them.

What are jetpacks?

Jetpacks, otherwise known as rocket belts or rocket packs, are usually used to transport a wearer through the air. These jets may consist of either expelled gases or liquids. Jetpacks typically consist of some form of back-mounted apparatus with handheld controls, and their concept has existed for a while.

In the 1960s, jetpacks sparked an interest in new films, notably in "James Bond: Thunderbird."

Working jetpacks come in a variety of forms and designs, but their real-life value is far inferior to how they are usually depicted in science fiction. This is for many reasons, but the main reasons are limited fuel, aerodynamics, gravity, and the human body''s ill-being in flight.

Jetpacks have had a much greater success in space, but they may help astronauts to maneuver effectively outside their spacecraft.

A number of jetpack prototypes have been developed.

These include, but are not limited to: -

  • Rocket-powered jetpacks
  • Turbojet jetpacks
  • Hydrojet jetpacks

The liquid-fuelled rocket packs are one of the oldest designs, with one of the early approaches which was once considered as early as 1919. Developed by Alexander Andreev, a Russian engineer who believed soldiers might use the device to leap across walls and trenches. The design actually received a patent, but was never constructed or tested. The Nazis later considered the idea for theirHimmelssturmer (heaven stormer) program, but they did not get far before the war came to an end.

Bell Aerosystems developed a two-jet pack called theBell Rocket Belt, which used hydrogen peroxide as a fuel. In fact, hydrogen peroxide rocket packs have historically been a popular jetpack design. They are powered by superheated gases released from hydrogen peroxide "fuel" degradation. This technique is effective but does not result in a reduced operating time. The Bell jetpack may only fly for 21 seconds.

Hydrogen peroxide-powered jetpacks benefit from being relatively lightweight and inherently safer. Other forms of hydrogen peroxide rocket packs were also developed throughout the 1950s and 1960s, including, mostnotably, a variation on the Bell Rocket Belt, which was used during the opening ceremony of the1984 Summer Olympic Games in Los Angeles, USA.

James Bond included Bell''s jetpack.

Many jetpacks, mainly fuelled with kerosene and jet fuel (sometimes also diesel), are typically more efficient and may fly for longer and higher, although they require simpler engineering and designs.

In most cases, this type of jetpack benefits significant from the inclusion of lift-generating surfaces, such as fixed or retractable winglets.

Another type of jetpack, called hydro jet packs, is designed to utilize high-density or concentrated fluids - usually water - to provide the same thrust and propulsion as exhaust gases in other designs. This approach, although relatively new, involves some form of flexible pipe attachment to supply the required liquid constantly.

This is because water is huge, and a lot of it is required, therefore carrying enough of it within a self-contained backpack is not feasible. However, this provides these jetpacks with some severe limitations, but they can, in theory, run for longer, so long as they have a steady supply of water.

Such jetpacks may be used for underwater propulsion.

Are jetpacks actually safe?

Jetpacks were the subject of eccentric daredevils and fantasy films until recently. However, after over half a century of refinement, jetpacks are perhaps moving into their own.

Aside from their limited flying time, the main reason for this commercialization delay has primarily focused on safety. Or, at least, their perceived safety.

While it is true that older jetpacks were intended to be too much of a wildcard to be seriously considered, modern jetpacks are a bit more promising.

Jetpacks may be safe to use with adequate training, experience, and regular equipment maintenance. However, as you can appreciate, one of the primary issues with jetpacks is the inherent risks associated with being propelled into the air with a scorching engine.

If something goes wrong, there are no real failsafe or emergency systems present; it is difficult to wear both a jetpack and a parachute, for example (the parachute typically needs to be attached to the jetpack itself), and the heat from the jetpack can quickly burn what is nearby. This is why those who fly jetpacks tend to fly over water or relatively close to the ground.

Accidents can and do occur even with the benefit of modern engineering. In recent times, the death ofstuntman Vincent Reffet was noted.

It is still unclear why his jetpack failed, but it appears the jetpack''s failsafe parachute did not deploy in time to save his life.

Other incidents have been recorded on camera, but have fortunately not been fatal. For example, one scientist,Dr. Angelo Grubisi, was horrifically crashed into the sea when his jetpack had a severe malfunction.

These, among other things, have, surprisingly, prompted many to question the actual utility and safety of the technology.

Why don''''t we all have jetpacks yet?

The main difference between the two is that it isn''t quite straightforward to make a jetpack. It''s simple to stick a miniaturized rocket onto your back, get it on, and get it done safely.

As much as that in movies like the Rocketeer, the reality of the situation could''t be further from the truth. For one, the human body is not well-suited for flying.

Auerdem, the user and the jetpack must deal with gravity.

While ensuring the jetpack is actually operatingable, there must be a solution to the problem, and there should be a fuel tank that maintains the safety of hot or dangerous gases or liquids away from the user and any surrounding people or structures.

Since a human being cannot carry tons of weight on its body, the dimensions and total weight of the jetpack must be adequate for larger automobiles, but these limitations are not as strict.

For this reason, most experts on the subject forsee jetpacks will be used for search and rescue, fire fighting, medical services, law enforcement, and the armed forces long before being widely available for leisure.

It''s also quite probable that we''ll not see large-scale jetpacks anytime soon. Custom jetpacks or jetpack experiences are of course a possibility. In fact, the latter already exists, but it''s also possible that the results will be later.

Despite all of these concerns, jetpacks have been developed. There are several exciting and promising jetpacks in the works, as well as some you can get started today!

Let''s take a look at some of them.

1.This UK-built jetpack is looking promising

Maverick Aviation, a UK-based business, unveiled their latest concept for a "universal jetpack" a few years ago. Engineers behind the jetpack leave nothing to work.

The jetpack is expected to be used by engineers, first responders, and maintenance workers to smooth and easy travel around difficult areas. The jetpack might also include excellent applications for militarization, security, and pure pleasure.

The jetpack includes an innovative autopilot system that can detect and respond to various problems, including low fuel or technical difficulties. In most instances, the jetpack will automatically land to protect the user''s life.

The Maverick jetpack can travel at speeds of up to 30 mph (48 km/h) and can be used in several ways to suit different applications better. For example, if it''s needed for heavy goods, it may be adapted to assist the user with payloads of up to 30kg.

At present, the jetpack is still in its development phase, but it might in the next few years shine.

They always say that, don''t they?

2.A jetpack from Gravity Industries is under investigation for emergency services in the United Kingdom.

Another hugely exciting jetpack project comes from the United Kingdom. It was conceived as theDaedalus Flight Pac, by a British engineer. This jetpack is more of a jet suit that differs from other concepts by the presence of additional thrust vectoring jets on the hands for greater maneuverability.

Browning, a former athlete and Royal Marine Reservist, used his unique vision to develop his jetpack in 2016 before foundingGravity Industries.

The Great North Air Ambulance Service in the United Kingdom is planning the jetpack ahead of them.

The jetpack, powered by 5turbines, is at a speed of 1050HP and can reach speeds of up to 85 mph (136 kph).

If everything goes to plan and the jetpack passes with flying colors, it is hoped that it may be used to permit paramedics and first responders to reach some of the most unaccessible areas of the countryside in short order. For example, it should be possible to contact someone in distress on a mountainside in a matter of minutes rather than hours.

Gravity Industries are also developing a leisure version of their jetpack suits. While it is unclear whether you can actually purchase one as yet, you may go to their site and test them for yourself (under controlled conditions).

Jet Pack Aviation has been in the news for a while now.

Jetpack Aviation, a business founded in 2016, has developed a variety of modified turbojet engines that run on a variety of jet fuels, including kerosene and diesel.

One, the JB10, has a maximum service capacity of 18,000 feet (5,486 meters), capable of reaching speeds of up to 120 mph (193 kph) and has a maximum flight time of eight minutes.

The JB10 is quite similar to the previous JB9, but it increases fuel capacity and thrust, as well as more sophisticated computer engine controls and pilot displays. When Mayman used the JB9 to fly around the Statue of Liberty in 2015, the company became famous.

The JB11, the JB10''s smaller brother, has an increase in fuel capacity and performance. It is heavier with a similar service ceiling and can reach similar speeds but is also improving endurance.

This model is developed using six turbojet engines and is specially designed for vertical flight. The engines are managed by a powerful computer system that balances the thrust from the engines, if the pilot encounters problems, and enables them to land safely.

Prices aren''t listed on their website, but you may contact the salesperson for a personalized offer.

The Martin Jetpack was one of the world''s first jetpacks, but is now being mothballed.

The Martin Jetpack, founded by Martin Jetpack in New Zealand, was commissioned for full license for crewed flights. The jetpack is one of the most unique designs internationally.

While the company was officially closed in 2019, you may still find the goods for sale online.

The manufacturer advertised its only operating model, the P12, as the "world''s first practical jetpack," which he described as "incredibly versatile, compact and straightforward to operate." The jetpack was also advertised as ideal for security (offense and/or defense), surveillance, emergency response, and recreational activities in its crewed and uncrewed versions.

The jetpack, apparently, had "pilot safety features," including" a fail-safe parachute that is capable of reaching up to 6 meters.

The jetpack is powered by a gasoline-powered internal combustion engine that can produce enough thrust to lift a weight of 220 pounds (100 kg) and has enough fuel to operate for an hour and a half and speeds exceeding a target of 5,000 feet (1,524 m).

All that is present is that the former major shareholder, Kuang-Chi Science, was looking for a buyer for Martin Jetpack''s remaining assets, but little is known about the condition of the P12.

5.Flyboard Air combines the concept of a jetpack with a hoverboard

Another interesting concept is this jetpack-slash-hoverboard called the Flyboard Air. This device was conceived by Franky Zapata, a French inventor, and is powered by a series of gas turbines and powered by kerosene.

When Zapata coaxed his Flyboard Air over a total distance of 7,389 feet (2,252 metres), he managed to set a Guinness World Record.

Zapata claims that the jetpack/hoverboard can reach an altitude of 9,800 feet (3,000 metres) and has a maximum speed of 120 mph (200 km), and that it also has ten minutes'' endurance and 120 kg load capacity.

The Flyboard Air has several key safety features, including a built-in redundancy if one or more engines fail. This allows the board to be put under control and safely landed before disaster strikes.

It also includes advanced stabilization abilities to increase the machine''s safety.

A 1.3 million euro grant has been paid to develop the Flyboard Air for military applications, although it may offer opportunities as a flying logistical platform or for assault activities.

The US Army has shown some interest in Zapata''s EZ-Fly version in the past, but did not pursue the issue further. The EZ-Fly is specifically designed for military or civilian use, with a lower learning curve and greater stability.

6.JetLev uses the power of water to get you airborne.

The JetLev hydro jet pack, which was first developed in 2008, was easily identified as one of the most suitable jetpacks for the consumers. Raymond Li then completed the pilot in 2000.

Li was able to obtain investment funding to construct some working prototypes after spending years deciding how to improve the design. He would later travel to America to finalize the design and invest further in production.

Li has been encrypting some clients who have hired out the JetLev packs for thrill-seeking travellers.

JetLev is derived from jetski technology. It is water-propelled and fed by an umbilical. It can lift an adult human about 30 feet (10m) into the air for extended periods of time. Many versions of the original JetLev are now available at affordable prices.

7.Yves Rossy''s jet wingpack is truly impressive.

Yves Rossy''s so-called wingpack is one of the most famous examples of more advanced jetpacks. When he was a Swiss military-trained pilot, Rossy took his flight adventure to new heights.

The most recent version of the jetpack includes carbon-fiber wings. The wings have a wingspan of approximately 8 feet (2.4 meters) and four Jetcat P400 jet engines.

These are modified versions of kerosene-powered model aircraft jet engines.

Rossy has continued to modify and test the design, including a solo flight over the Alps Mountain Range in 2008.

During this journey, his jetpack was capable of reaching speeds of 189 mph (304 kilometers) (Figure 1). In 2009, he attempted but ultimately failed to cross the Strait of Gibraltarbut managed to cross the Grand Canyon in 2011.

Rossy and Vince Reffett performed a choreographed demonstration flight with an Airbus A380 at 4,000 feet (1,219 metres) altitude in 2020. He demonstrated how his latest jetpack evolved to a horizontal flight.

These are one of a kind, but it is unlikely that they will be mass-produced anytime soon.

Today, it''s your lot for today.

While jetpacks are still evolving, we will begin seeing them in specialist roles in the future. It''ll take another year for everyone, and it''ll take a few years for you to get one on your daily commute.
