Arbeiten am Department Fahrzeugtechnik und Flugzeugbau, Prüfer: Prof. Scholz

Some tasks below are written in German and others in English. Of course every task can be done in either language. I did not go through the trouble of writing everything in both languages. German students can understand both and can decide in which language they want to work and write. International students, please ask me for a translation if a task described in German seems interesting for you.

I have been approached by students saying they want to get their credit for a project (or thesis) with as little work as possible. Other professors would be offering projects requiring very little work. In order to compete also in this race for lowest effort, I offer "Easy-Going-Projects". Time for the investigation is very limited, however, I can not compromise on writing style. Students will have to deliver a report written to scientific standards with proper references. "Easy-Going-Projects" can also be team projects. In this case, the limited work is even shared in the group. In any case, the report will look ok, but for the individual their is very little work due to limited scale of the task.

Viability of Hybrid Electric Propulsion for Passenger Aircraft

Realisierbarkeit hybrid-elektrischer Antriebe für Passagierflugzeuge

Project or Thesis Passagierflugzeuge mit Reichweiten, wie wir sie heute kennen, werden rein elekrisch mit Batteriespeichern wohl nie zur Anwendung kommen. Anders könnte es in der Zukunft aber sein, wenn die Energie in effizienten Kraftstoffen an Bord gespeichert wird, die dann vor Ort mit Generatoren in Strom für Elektromotoren gewandelt wird.

Electric propulsion will only have a chance for passenger aircraft, if energy is stored on board efficiently in fuel with high energy density which is converted in generators into current for the electric motors. Read here, find out more and discuss in you project or thesis:


Follow this analysis for GA and do the same for aircraft with more than 100 seats and especially with minimum "medium range":

Debunking Aeronautical Engineering Myths

Mythen des Flugzeugbaus entlarvt

Project A fuel cell produces electricity with higher efficiency than a generator connected to the aircraft engine. Aircraft fly high to save on drag. SFC (Thrust Specific Fuel Consumption) is constant in a first order evaluation. Winglets improve wings. Wave drag is difficult to calculate. The drag coefficient starts to increases at Mach numbers beyond normal cruise speed. Aircraft should fly at their optimum speed which is quite high. An aircraft uses more fuel when it flies lower. Low Cost Airlines are the cause for additional fuel consumption and pollution. We have to reduce CO2 to save the world. The aviation industry does the utmost to save the environment. --- Is it all true? available
Verifying a Simple Method for Mental Arithmetic Converting CAS to TAS

Überprüfung einer einfachen Kopfrechenmethode zur Umrechnung von CAS in TAS

The method is used by pilots flying faster aircraft. The simple method is explained here
http://www.fzt.haw-hamburg.de/pers/Scholz/materialFM1/1-19.JPG (unten)
The correct calculation is shown here to work well (as far as this one example is concerned):
Prove with varying input parameters and/or with some kind of prove that the method has general validity.
Software Testing: Rapid Air System Concept Exploration (RASCE) Project or Thesis RASCE is an Excel-based aircraft design tool which is offered as "Complimentary Program" to OpenVSP (www.openvsp.org). RASCE comes in four versions. We are most interested in the turbofan design tool. Check out the tool and redesign a selected aircraft. Compare with the aircraft design tools used in my lecture (http://fe.ProfScholz.de) and research group (software will be provided). You could even compare with ADAS (see task below). What can we learn or add from RASCE?
RASCE for Turbofan Aircraft:
Software Testing: VSPAero Project or Thesis VSPAero is based on linear potential flow theory and represents thickness via panels on the surface to a limited extend. Results, however, are very much like those from vortex lattice methods as known from e.g. AVL or Tornado. Check out the tool and calculate the aerodynamic characteristics of a selected aircraft. Compare with Tornado (http://tornado.redhammer.se). Links:
VSPAero is integrated into OpenVSP and is included in the download:
The Fuel Consumption of Extreme Long and Short Flights Project The average fuel consumption expressed in kg/100 km is relatively high for very long flights, but also for very short flights. Plotting the fuel consumption of the aircraft versus flight distance we expect to get a typical "bath tub curve". Plotting the fuel consumption per passenger versus flight distance has to take the number of passengers on board into account which is decreasing with increasing range. Input to these calculations requires knowledge of the aircraft's mass, aerodynamics and specific fuel consumption of the engines. Since not all of this is in the public domain, methods have to be found how to extract the data from published payload range diagrams. available
Optimum Aspect Ratio for a Blended Wing Body (BWB) Aircraft Project BWBs benefit from a low S_wet/S_W but suffer from a generally low aspect ratio. So, why not increasing the aspect ratio of BWBs to have both and enjoy a high (L/D)max? Preliminary aero and structure estimates should give an answer. available
Proposing a Classification for Aeronautics, Astronautics, and Aerospace Sciences Project Classifications - the heart of science. Examples of classifications: DDC, ICD-10, ... Standards for creating classifications. For the task here, please have a look at this: A first idea to get started. What else exists in our field? available
Aerodynamics of the Maple Seed


Die Aerodynamik des Ahronsamens

Depending on depth: Project or Thesis A maple seed spins about itself and falls gently down to earth. How much slower is this than free fall? What are the aerodynamics to calculate the answer to this questions?

My initial review on the Internet showed:
David Lentik from Wageningen University, Netherlands

I am not convinced. It is not the answer to my question. Maybe better along this line:
https://de.wikipedia.org/wiki/Ahorne#Fr.C3.BCchte_und_Samen / https://en.wikipedia.org/wiki/Maple
https://de.wikipedia.org/wiki/Autorotation / https://en.wikipedia.org/wiki/Autorotation
https://de.wikipedia.org/wiki/Tragschrauber / https://en.wikipedia.org/wiki/Autogyro

We can make it very simple at first and we will get a quick answer. Later we can follow this path:

Analytical Balanced Field Length Estimation Thesis Calculation of the balanced field length (BFL) traditionally involves a numerical calculation, where the various forces are evaluated as a function of speed, using a step-wise integration and an estimate for V1. The process is iterated with different values for the engine failure speed until the accelerate-stop and accelerate-go distances are equal. Are there simple analytical methods to estimate BFL? (See: Thesis Ehrig, SAE-Paper or Raymer) available

Leitwerksdimensionierung mit dem Volumenbeiwert - Grundlegende Statistiken

Empennage Sizing with the Tail Volume Coefficient - Basic Statistics


We investigated the Tail Volume Coefficient already well (see Technical Note Ch. 2.5.2 and 3.1). What we need next is an evaluation and estimation of the lever arm measured from the wing to the tail in preliminary aircraft design. The lever arm is a percentage of the fuselage length. First hints are given in the lecture notes "Aircraft Design", Chapter 9. We need to rework and improve the topic.

Evaluation of the Aircraft Design and Analysis Software (ADAS) Project ADAS is an Excel-based tool written at the University of Naples. Try out the program and write about your experience with it. Here in the 2011 EWADE Presentation you can get a first idea of what it is all about. available
