Chapter 10: No 335 CLT (Center Line Thrust) Light Aircraft

1. Comparison between No 335 compared to Do 335: Notice the engines installation at both ends of their fuselages. 

In 2006, I wrote and presented a paper, "ADVANTAGES OF DORNIER DO 335 CENTER LINE THRUST (CLT) AEROPLANE COMPARED TO WING MOUNTED TWIN ENGINES AEROPLANE OF THE SAME CLASSIFICATION AND A PROPOSED DESIGN FOR CLT AEROPLANE" at an engineering conference in Putrajaya, Malaysia. The most significant feature of Do 335 is its center line twin engines configuration, where one is installed at the front-end and another one is installed at the rear-end of its fuselage. This CLT (center line thrust) light aircraft concept is employing the same engine configuration and therefore is called, "No 335". It has many unique features compared to conventional light aircrafts.

2. Top view of No 335: Notice the transparent canard.

However, unlike Do 335, which is a single-seat ground attack aircraft, No 335 is a concept for 2-seat aerobatic, recreational and training aircraft. No 335 also has its straight wing on the rear and straight transparent canard on the front of its fuselage respectively. The canard is made transparent to improve the view downwards from the cockpit.

3. Side view of No 335: Notice the seating configuration, engines installation, front engine outlet & rear engine intake.

No 335 have seats for 2. They sit in tandem with the pilot at the rear and higher than the passenger at the front. No 335 is powered by 2 electric engines, both rotating 4-blade propellers in contra-rotation for torque cancellation. The front engine has an air outlet below the front seat, and the rear engine has an air intake below the rear seat to air-cool both engines. The fuselage was designed to be in such a way for the smart installation of those seats, engines, intake and outlet.  Another unique design feature of No 335 is its vertical stabilizer which has a length greater than its height.

4. Front view of No 335: Notice the "Stuka-style" wing & transparent canard.

The wing of No 335 is of "Stuka-styte". This is to allow installation of short main landing gear under the wing.

5. Ju-87 Stuka: Notice the design of its wing to allow the installation of short main landing gear.

6. Bottom view of No 335: Notice the transparent canard, rear engine intake & landing gear doors.

No 335 is a "DNA" for my other CLT concept aircrafts, just like ADIB and Why600 are the DNA for my other quadcopter and Y-fuselage concepts respectively (see ADIB & Why600).

The 7 Advantages of CLT Aircrafts compared to Wing-mounted Twin Engines Aircrafts

1. CLT aircrafts are more aerodynamic because they have clean wing and smaller frontal cross section area,

2. CLT aircrafts do not lose their symmetry if 1 engine fails because both engines are on the centerline.

3. CLT aircrafts are safer for emergency landing when 1 engine fails because they don't lose symmetry.

4. CLT aircrafts are more maneuverable because both engines are on the centerline.

5. CLT aircrafts can be built with lower cost because their wing can be lighter and shorter.

6. CLT aircrafts can be kept inside a smaller storage because their wing are shorter.

7. CLT aircrafts have higher rate of survival for ground attack mission because they have shorter wing and better maneuverability.
