777 vs 787: A Comparison of the Two Boeings
Aircraft · 7 min read
The Boeing 777 and 787 are two of the most popular commercial airplanes currently in service when it comes to wide-body, twin-engine jetliners.
The Celera 500l is a new type of private aircraft developed by William “Bill” Otto, the founder of Otto Laboratories in 1974 and head of Otto Aviation Group since 2008. The aircraft was designed to tackle air travel problems that William Otto identified as an air traveler himself over the years. Some of the main issues identified include:
With these problems in mind, Otto and his team developed the Celera 500l as a solution that would make a reality having the convenience of a private aircraft at low cost and with a reduced carbon footprint in a commercially viable aircraft.
The Otto Aviation Group is a Limited Liability Company (LLC) created to have a team helping William Otto with the development of the Celera 500l to the point of getting FAA certification for its production. The company relies on a highly-trained team of experts in different areas such as physics, engineering, aeronautics, fluid dynamics, materials, structures, avionics, landing gear, hydraulics, and flight testing.
When visiting the company website, a series of impressive features of the Celera 500l jumps to the eye. Otto Aviation presents the following numbers:
Apart from the numbers above, they also claim that the Celera 500l design allows a transcontinental range for direct flights with operating costs equal to or better than commercial airfares.
Also, Otto Aviation mentions that the Celera 500l design achieves extremely low drag across the entire aircraft through extensive use of laminar flow surfaces for the wings, fuselage, and tail sections. Let’s take a closer look at the latter.
When it comes to fluid dynamics, there are two possible types of flow, turbulent and laminar flow. In aviation, the laminar flow is desired, and the turbulent flow is avoided as much as possible. This is because turbulent flow on the aircraft surfaces increases skin friction drag, resulting in reduced aerodynamic and fuel efficiency. Obviously, the opposite happens when we have laminar flow since the air moves in smooth layers. A significantly reduced drag makes the aircraft more aerodynamic and fuel-efficient.
Based on this, if Otto Aviation has made it possible for the Celera 500l to be full of laminar shapes, then the Celera 500l could be the most fuel-efficient aircraft in the sky.
Everything sounds impressive so far, but is this really inexpensive?
This is an aspect that must be looked at with perspective. While the price tag of an aircraft like the Celera 500l might be a huge number, beginning with the engine that reaches a $230,000 price and Bill Otto saying they are targeting the Pilatus PC-12 price range of $5 million, owning a Celera 500l could indeed be good business.
We already mentioned that the Celera 500l could offer operating costs of around $328 per hour. Assuming seats can be sold at the same price as equivalent first-class seats, the six passengers in the Celera 500l could provide about $6000 per flight, which translates into significant profitability. It is true that since the pandemic, these numbers may be feeling the pressure and will be lower for quite some time, but still, at an economic-class range per seat, there’s some profit to take.
Now, you may wonder how all these compare to a similar jet aircraft. Let’s see.
When matched with comparable jet aircraft, the Celera 500l may seem unbeatable if the claims made by Otto Aviation become a reality.
It is essential to highlight that Otto Aviation has not validated all the claims they have made. The Celera 500l has only taken around 30 test flights since it was seen at Southern California Logistics Airport for the first time. It has done it with an engine different from the one it will be carrying once production starts at Otto Aviation premises. Therefore, the Celera 500l has not achieved the cruise speeds and higher altitudes it was designed for.
The difference with a comparable jet aircraft such as a light jet could be summarized as follows.
Private aviation has moved from an independent operation to a more air taxi kind of model. With the current fears created by the pandemic, more wealthy people will look for a more private way of air travel. The Celera 500l is ready to disrupt the air taxi market with a cost comparable to any other private jet. This new type of aircraft offers enormous market opportunity, especially if it can be adapted for other applications such as cargo operations, military applications, drone-like activity, and electric or hybrid format. Only the future will tell.
