VTOL Aircraft – The Future Of Aviation!

VTOL aircraft

Aircraft have been rapidly advancing since the wright brother’s first flight at kitty hawk. Gliders, helicopters, and even blimps have developed better technology as time progress. One area in aviation that is improving is VTOL aircraft.

Vertical Takeoff and Land (VTOL) aircraft are vehicles that can take off and land vertically, using little to no ground roll. When in the air, some can switch thrust direction to move forward at faster speeds. These aircraft can take off like a helicopter, then fly faster than most fix-wing planes. These capabilities allow for taking off and landing in tight spaces.

These aircraft have been around for a while now. As technologies improve over the years, new implementations and missions were found doable because of VTOL abilities.

History

Hawker Siddeley Harrier AV-8S was a VTOL aircraft that was used by the Royal Air Force and USA Marine Corps. Its first flight took place on 28 December 1967. It was the first operational VTOL aircraft and had the only genuinely successful Vertical and/or Short Take-Off and Landing (V/STOL) design at the time.

VTOL AV-8 aircraft

 

An improved version of the aircraft was developed about ten years later. The plane was the McDonnell Douglas AV-8B Harrier II, which first took off November 9, 1978. It was one of the most famously known VTOL aircraft at the time. This VTOL military aircraft was commonly used in movies and video games. It was rare for a fighter jet to have the capabilities of taking off like a helicopter, then travel at speeds up to Mach 0.9!

The aircraft have jet nozzles on the fuselage. These vents could have rotated depending on the phase of flight. If it were not for these jet nozzles, then the VTOL abilities would not have been possible.

The av-8b harrier was very successful and was enjoyed by pilots. Capt. Michael Wehner , a previous Harrier pilot for the Marine Corps, said, “ The Harrier gives the ground commander a pretty big hammer he can deploy from a base.” It was an ideal military machine. The aircraft served its time and retired back in 2006.

Military Operation

F-35B VTOL

The most recent VTOL military aircraft that pilots can fly is the F-35B lightning 2. This fighter jet was produced in 2006 and entered service with the US Marine Corps in July 2015. The advantages the aircraft have over the AV-8B harrier are:

  • Faster
  • Greater range
  • Stealth Technology
  • Can carry more weapons
  • Easier to fly for pilots

According to Maj. Paul Greenberg, of the Office of U.S. Marine Corps Communication, “The F-35B supports our doctrinal form of maneuver war-fare, and our tactical and operational need for close air support in austere conditions and locations potentially inaccessible for traditional fighters”. The aircraft was made to get in the air quickly and complete missions successfully.

The F35 VTOL system included a lift fan in the middle of the aircraft and the main engine in the back. The engine in the rear was capable of “twisting downwards” to provide the vertical lift needed. The lift fan only operated during VTOL operations. This meant vertical lifting took place because of these two propulsion systems.

V22 osprey

 

Another well-known VTOL aircraft is the Bell Boeing V-22 Osprey. It first flew in 1989 and is used by the US Marine Corps. The V22 Osprey has two large turboprop engines that can change direction!

When on the ground, the propellers are facing upwards for VTOL capabilities. After the osprey plane is in the air, it then moves forward so that faster flight speeds can be achieved. So for VTOL operations, propellers are perpendicular to the aircraft longitudinal axis. For high speeds, they are parallel to the plane longitudinal axis.

Creating an aircraft like this was a huge challenge for engineers, as it was a bizarre aircraft. It was the world’s first production tilt-rotor aircraft, so a lot of research and test had to be done. The plane needed to be able to fold the wing and rotors so it can be stored on ships and small spaces. Considerations as to how pilots can maintain control from transitioning between modes were looked at carefully.

Unmanned aerial vehicle (UAV) VTOL aircraft are commonly used for military operations. These aircraft do not have pilots in them. The drone pilot is at a station commanding it remotely. UAV allows for dangerous activities to occur without risking a pilot’s life. UAV VTOL aircraft are used for:

  • Dropping supplies or weapons
  • Surveying an area
  • Assist ground personal

City Transportation

Many aerospace companies such as Boeing, Airbus, Bell, and Uber are developing VTOL air taxis. These VTOL aircraft are large drones that can carry human beings or cargo. It is a new market that is looking to be implemented in everyday life very soon.

Air taxis aim to transport people or goods faster and more efficiently in large cities such as New York, Singapore, and London. Transportation with cars in these cities can waste a lot of time. Flying over traffic and reaching your destination should be quicker and more pleasant.

VTOL air taxis are expected to be 100% electrically powered. This helps promotes greener energy use for transportation. This also means noise pollution should not be an issue during operations.

Current regulations, safety, and today’s technologies are posing some challenges to engineers. However, they are a lot of flying prototype which showcases how these vehicles will operate.

Is This The Future?

An article written by the National Association of Securities Dealers Automated Quotations (NASDAQ) Solution stated:

“Aircraft have been the most powerful tool for various military and non-military applications. These systems have constantly been evolving at a rapid pace, due to their extensive growth in these fields (in the military and commercial sector.”

New VTOL aircraft are being developed and created every day. It appears there is a large prospective market in this area in aviation. Some of these aircraft are being used and operating right now. New designs are approving of aircraft which can take off with little to no runway and operate at higher speeds.

  1. I love this. I love everything to do with aviation. Having a family member being in the US Air Force before this has gotten my interest. I am so happy to have stumbled upon your post. Boeing V-22 Osprey is a fascinating aircraft. I do think that VOTL aircraft will become more popular in the near future. Which avenue do you think will be the first to use it the most, talking future wise?

    1. I think it will be more popular, especially in urban transportation. Flying without needing a long takeoff run is becoming more popular. This is a reason why drones are a favorite for many.

  2. The future of aviation sounds very exciting!

    I learned so much from reading your article today and I, for one, am certainly curious to see what the future brings for this industry.

    Having worked in the transportation industry for 26+ years, I am particularly interested in the potential of air taxis.

    Thank you for a very interesting and informative article.

  3. It is definitely interesting where technology is going in regards to flight. Science fiction has depicted air-taxis for a while and now it looks to become a reality. What could become popular is personalised autonomous flying cars, operating your own flying-car might be too much for the average human.

    1. I think having flying cars and operating them as the vehicles on the ground will not happen for a while. Safety, training, and cost are just a few obstacles that have to be fixed. Air taxis however are looking more promising.
