Stratos 714 Design


The Stratos 714 will cruise at Mach 0.7, yet have approach speeds comparable to piston singles. The key to achieving these competing demands is the Stratos 714’s unique airfoil and wing design.

The aerodynamics of the Stratos 714 is being developed using modern Computations Fluid Dynamics (CFD) software along with empirical processes. Developing an aircraft capable of flying at 400 knots but with excellent handling qualities at 80 knots was a tough challenge. We’re sure you’ll be happy with the results.

Stratos 714 Engine


The Stratos Proof of Concept is powered by the highly efficient Pratt & Whitney Canada JT15D-5:

• EEC (Electronic Engine Control) system with hydromechanical back-up: ease of pilot workload.

• Efficiency: single engine turbine reduces operating cost significantly.

• Reliability: more than 6,600 engines produced having accumulated more than 41 million hours of flight time.

• Confidence: supported by P&WC’s industry-leading global customer support.

• For the certified aircraft, the P&WC PW535E will be used.

Why Single Engine?


An obvious question is “why single engine versus twin engine?” The primary reasons are increased safety (see below), lower costs (acquisition and operating) and simplicity for the operator. As a result of the proven reliability of modern turbine engines, single engine aircraft are widely accepted today.

General aviation accident statistics are consistent in showing flying to be safer in single engine than in twin engine aircraft. Further, the statistics show that occupants are more likely to survive an engine failure (which situation is twice as likely in a twin) if it is the only engine. Convinced by these safety statistics, the FAA, has allowed single engine commercial IFR flights since 1995. The evidence accumulated since then shows that single engine turbines are the safest of all general aviation aircraft types.

The Stratos Configuration advantage


A single engine jet has many advantages over a twin engine jet. However it poses the question of the optimum location for engine placement.

The general aircraft layout including engine placement is referred to as “configuration”. Early in the program, considerable time was spent studying various configurations prior to settling on bifurcated inlets with the engine mounted centrally in the fuselage. This was primarily the result of three considerations:


Maintenance


The Stratos 714 is designed with maintenance in mind. A maintenance management system will be integrated within the avionics suite to track and alert for required maintenance.

Flying the 714


Flight Characteristics


The flight characteristics of the Stratos 714 are designed for the individual who owns and operates his own aircraft; docile flight characteristics and a low pilot workload are major design drivers. While we anticipate that buyers of the Stratos 714 will include professional pilots, that level of expertise and experience is not required to safely fly the Stratos 714. The key design attributes which support these flight characteristics include the following:

The key design attributes which support these flight characteristics include the following:

Stable and predictable flight characteristics


In choosing the configuration of the Stratos, stability was a major design driver. By installing the engine relatively forward the Stratos has a long tail arm (this is the relative distance between the horizontal tail and wing).

Also the thrust line is close to the center of gravity reducing pitch changes with power changes. This is different than engines mounted far aft, that result in a relatively short tail arm.

Simple and automatic systems


By designing simple and/or automatic systems the pilot workload is further reduced. In addition to the required autopilot, automatic environmental controls and other systems will reduce pilot workload. Our guiding philosophy in designing for safety is to prevent the accident in the first place. In 2005, 76% of all general aviation accidents were attributed to pilot error.

High Altitude Operations


The Stratos 714 is pressurized and equipped for flight up to 41,000 ft (maximum certificated altitude). The advantages of high altitude operations include improved efficiency, longer range, and being able to fly above most of the weather. However, high altitude flight poses a new set of issues that must be carefully addressed in terms of design and pilot training.
